SAT/ACT, Chemistry, Physics, and Calculus Specialist

The costs of college have never been greater, and they are expected to continue growing. Further, admittance into the best colleges is more competitive today than at any point in the past century. Investing in your student's education now might net them a handsome scholarship, and a more flexible future. If student loans will be necessary to pay for college, your student (and quite possibly, the cosigner) are especially vulnerable post-graduation. STEM fields have been touted as the future o...

Algebra 1

Algebra I is a very important subject to learn well, as future success in Math hinges upon it. Many students become disinterested in math as a subject due to Algebra I, second only to Algebra II. It is critical to have a solid understanding of Algebra I if any type of math is in your future. Topics such as factoring quadratics, linear equations, and simplifying fractions are often forgotten once a student finishes the course, and can lead to devastatingly low test scores years down the road. I've tutored Algebra I since I took it in high school and have been tutoring full time for four years now. Please consider me as a serious candidate to aid your student for this course.


Algebra 2

Algebra II can be a very tricky subject for students. Although it begins with the natural marriage between Algebra I and Geometry, students can have difficulty transitioning from Geometry to Algebra II because they haven't thoroughly used their Algebra I skills for over a year. Furthermore, Algebra II introduces topics far more complex than those discussed in Algebra I or Geometry. Topics such as graphing rational, polynomial, and trigonometric functions include as many as ten steps in their most thorough forms, as compared to the three, maybe four step processes present in previous math courses. Some Algebra II courses also include a topic called conic sections, which is particularly elaborate. Bottom line, Algebra II is the math class that will either make --- or break --- your student. It can propel them to more advanced classes or discourage them from taking math entirely. I have tutored Algebra II since the year after I took it in high school, and I've been tutoring full time for four years. Not only am I well versed in Algebra II curriculum, I've created step-by-step processes for each of these topics. Please consider me as a serious candidate to aid your student for this course.


Calculus

To many students (and parents who remember it from college), Calculus is a dirty word. Though many struggle with it, Calculus is a powerful math course in its many forms. Whether or not your student is interested in mastering this broad and diverse topic, Calculus will likely be the most challenging math course they take in high school. Should a student desire a degree in science or engineering, it is likely that they will delve much deeper into Calculus I, Calculus II, Multivariable Calculus, and Differential Equations. If this is the case, a rock-solid foundation is tantamount to their success. My degree is in both Physics and Applied Mathematics, though most of the math courses I took in college were Calculus courses. I have a strong command of this material and I thoroughly enjoy teaching it. I believe this level of enthusiasm clearly sets me apart from other tutors. Please consider me as a very serious candidate to aid your student for this course.


Chemistry

Whether your student's goal is to get through Chemistry or build their resume with their standardized test scores, they'd perform best with some help. I begin Chemistry tutorials with probing questions to determine the size and scope of the particular class your student is in. Afterwards, I put my ten years' experience to work, illustrating to them how to do the work and why we are doing it this way with historical perspectives. Please consider me as a serious candidate to aid your student for this course.


Geometry

I can give your student the information they need in order to perform well in Geometry and show them why it is mathematically important to do so. I've been tutoring Geometry since I took it in 2002, and I have four years of full-time tutoring experience since 2013. Please consider me as a serious candidate to aid your student for this course.


Physics

Physics is the most mathematically oriented science your student will see in high school. It requires both the memorization of complex procedures and a strong command of Algebra, Trigonometry and, in some cases, Calculus. It is critical if your student plans to study STEM, even if they want to study a science like Biology. If your student performs well during an AP Physics Course (AP Physics 1, AP Physics B, or AP Physics C) they may be able to opt out of Physics classes in college. AP exams can save credits and allow them to either graduate early or take classes more directly related to their major. Physics is one of my favorite subjects to teach. I have spent two years in high school, then four years in college tutoring this subject and perfecting step-by-step procedures to attack problems dealing with kinematics, Newtonian mechanics, energy, angular and linear momentum, circular and rotational motion. Please consider me as a very serious candidate to aid your student for this course.


Prealgebra

Now that your student has made it through Algebra II, it's time to start gearing up for them to learn Calculus. Turns out, there is a year's worth of work that needs to be done before Calculus. It is now that your student must master the unit circle, conic sections, limits, inverse trigonometric functions, complex numbers, and alternate coordinate systems. Whether Pre-Calculus is the last math course your student will ever take or they plan on a career in Mathematics, this course can be particularly challenging. I have four years of full-time tutoring experience, and I've been tutoring Pre-Calculus since 2005. Please consider me as a serious candidate to aid your student for this course.


Precalculus

Now that your student has completed Algebra II, it's either time for their final math course of their high school career, or it's time to gear up for them to take Calculus. As it turns out, there is a year's worth of work that needs to be done before your student is ready to take Calculus. Pre-calculus is your student's last opportunity to master topics such as the unit circle, conic sections, limits, inverse trigonometric functions, logarithms, sigma notation, series, and complex numbers. After this course, your student needs to know these topics intrinsically. These are challenging units to get a commanding hold of. I've been tutoring full time for four years and I've been tutoring Pre-calculus since 2005. Please consider me as a serious candidate to aid your student for this course.


Trigonometry

Trigonometry is the mathematical study of the relations of angles to side lengths. Trigonometry commonly is taught with Algebra II, which is a subject many high school students find difficult already. It also arises on the New York Regents Exams. I've been teaching Trigonometry privately since 2005 and I find it easiest to comprehend when it is broken down into a few different sections. Please consider me as a strong candidate for tutoring this subject.


SAT Math

The SAT is said to be the most important pre-collegiate test. A ten point difference can mean acceptance or rejection by any institution, not to mention the sizable difference in financial aid packages. I scored a 780 on my Math portion of the SATs, and I can help maximize your score. Fortunately, the Math sections of the SAT include question topics which can be learned and practiced. Unlike the verbal portions for which one is expected to learn a large quantity of vocabulary words, techniques can be learned for each type of question in the mathematics sections, improving the score by a larger degree than in the verbal sections.


GED


PSAT

The PSAT is a test that is designed to give your student a "taste" of the SAT. It is scored differently, and is usually given during the fall of junior year (and sometimes the fall of sophomore year). The reading and writing sections are likely more difficult than anything your student has seen up to this point, and require a well-honed ability to pinpoint the author's intent and the rhetorical devices they employ. The math section can be even shakier. Since your student is likely just beginning to take either Geometry or Algebra II during this time (if they are taking Pre-calculus they may be already well versed for the math sections) it is unfortunate timing for the test. Your student may not have had the instructions necessary to do well on this test, and for that reason, sometimes receiving the scores back is scary. An often overlooked fact about this exam is that if your student performs exceptionally, landing within the top 15,000 students (roughly), they may become a finalist for the National Merit Scholarship. If your student's goal is to score very high on the actual SAT (or ACT) then preparing for this test can not only give them a solid test-taking foundation, but also net you some dollars. I've been tutoring full time for four years, and I have a thorough command of these kinds of standardized tests. Please consider me as a serious candidate to aid your student for this exam.


SSAT

If you wish you student to gain admittance to an accredited private school, chances are they will be required to take one or more standardized tests. One such test is the SSAT, which tests their ability to understand usage and rhetoric based questions for verbal and reading sections as well as analogies. A powerful vocabulary is also necessary to score well on these sections. The math portions of this exam test topics your student has sometimes never seen before as well as harder versions of questions they have seen already. The essay portion of this exam is not graded, but sent to the schools your student is applying to. The essay can be challenging for students who have never been required to analyze the legitimacy of arguments they --- both --- agree and disagree with. I have four years of full time tutoring experience dealing with these standardized tests. I can not only teach your student the topics they will need to know, but also the techniques required to score well on this exam. Please consider me as a serious candidate to aid your student for this exam.


ACT Reading

The ACT Reading section consists of four passages, three of which can be effectively skimmed for content. I teach your student how to ask "SO WHAT?" while reading which will allow them to quickly and reliably determine the author's message. I also show them how to abuse the author's punctuation to get a faster sense of the purpose of a paragraph. When they read in this manner, they are more prepared to answer the questions and spend less time searching for the necessary information. Each student is given a binder which will archive all of the exams taken and catalog the errors they've made with specific notes about the topic like "primary purpose" or "rhetorical goal of a paragraph" instead of broad generalizations made by many other tutoring companies. Lessons are given on the topics with which they struggle most and additional assignments are provided to ensure they retain and can use the information they've been given. Their progress can be tracked over time, and their score progression can be a very rewarding sign of their progress!


ACT English

The ACT English section is arguably the section able to be improved the most on the ACT. Its questions are comprised of basic usage including comma usage, compound sentence punctuation, subject-verb agreement, and possession rules as well as stylistic rules such as the rhetorical purpose of a passage, paragraph, sentence, or transition word. I teach your student the critical rules of usage necessary for the ACT and specific strategies for tacking rhetorical questions raised by the exam. Once a student has mastered these topics, there is very little keeping them from scoring very well on this first of the "big four" sections of the ACT. Each student is given a binder which will archive all of the exams taken and catalog the errors they've made with specific notes about the topic like "comma usage" or "rhetoric of a transition word" instead of broad generalizations made by many other tutoring companies. Lessons are given on the topics with which they struggle most and additional assignments are provided to ensure they retain and can use the information they've been given. Their progress can be tracked over time, and their score progression can be a very rewarding sign of their progress!


ACT Math

The ACT math section is a broad-ranging examination and includes topics from Algebra I, Geometry, Algebra II/Trigonometry, and a small bit of Pre-Calculus. Though answering sixty questions in sixty minutes sounds like a daunting task, time can be managed more effectively on the ACT because of the test's ability to be manipulated, or "hacked." All diagrams on the ACT are drawn to scale, a calculator is allowed throughout the entire section, and all questions are multiple choice. For many of the questions it is possible (and even more efficient) to get the question correct using a particular technique rather than doing the problem in a pure mathematical way. I have extensive experience in teaching both the strategy of this section and the pure math for those students who are looking to score exceptionally. Each student is given a binder which will archive all of the exams taken and catalog the errors they've made with specific notes about the topic like "direct variation" or "circle geometry" instead of broad generalizations made by many other tutoring companies. Lessons are given on the topics with which they struggle most and additional assignments are provided to ensure they retain and can use the information they've been given. Their progress can be tracked over time, and their score progression can be a very rewarding sign of their progress!


ACT Science

The ACT Science section can seem very scary to those unfamiliar with the ACT because a the highly recognizable name brand SAT contains no science section. Though the science section on the ACT contains higher level science than what is classically taught in high school, this section turns out to be very manageable. I encourage students to keep six things in mind while they read one of the seven passages in the science section: What are the independent variables? What are the dependent variables? What are the controlled variables? Is there a control group? Were any assumptions made during the design of the experiment? What do the different experiments have to do with one another? By attempting to answer these questions during the student's reading time, they come to understand the experiment in greater detail and are well prepared for the questions at the end of each group of six questions or so. Each student is given a binder which will archive all of the exams taken and catalog the errors they've made with specific notes about the topic like "table reading - read between the lines" or "identify the assumption" instead of broad generalizations made by many other tutoring companies. Lessons are given on the topics with which they struggle most and additional assignments are provided to ensure they retain and can use the information they've been given. Their progress can be tracked over time, and their score progression can be a very rewarding sign of their progress!


Elementary Math


Elementary Science


Differential Equations

I took Differential Equations in college, as well as partial differential equations, and how to model differential equations in C. This is usually the most advanced math course taken by most engineering students. Differential equations (or affectionately "Diff-E-Q") aren't so much unlike normal calculus problems in which one solves for an unknown, except that the unknowns in this case are other functions entirely. Instead of having just the variable in the equation, you have the function and derivatives of that function. In other words, it is the pinnacle of Calculus, its final destination (for most students). Unlike most other math disciplines, DiffEq can have more than one answer. This it a really profound conclusion, as it finally provides a "gray area" of math, with each solution given a different amount of credence. It is a worthy subject indeed.


ISEE

If you wish for your student to attend a private school, it is likely that they will have to take one or more standardized tests. One of the most popular exams in this respect is the ISEE. This test is extremely challenging, particularly the upper level ISEE. Your student will be competing against other students who have historically been well supported in their academic careers. The test contains material your student has likely --- never --- seen before. In order to perform well on the ISEE, a large amount of preparation is crucial. This test has five sections: Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, Mathematics Achievement and the un-scored Essay portion. An extensive vocabulary along with an ability to infer the meanings of words is most important on the Verbal Reasoning section. To do well on the Reading Comprehension section requires your student to read for the intent of the author along with their rhetorical techniques, which is usually a new idea for students. The Quantitative Reasoning and Mathematics Achievement sections require mastery of topics your student has already seen as well as significant training in topics they haven't yet seen. The essay portion of the exam can be tough for students who haven't yet had to argue a point and defend it by acknowledging arguments and supporting or refuting their credibility. This test can be brutal, but I have four years of full-time experience with it. I can teach your student not only the topics they will need to know, but strategies to conquer this mountain of a test. Please consider me as a serious candidate to aid your student for this exam.


Linear Algebra

Linear Algebra might sound easy ("Linear, that's like lines, right? I know those!"..."Algebra, I know Algebra inside and out!") but combine the words in that specific order and you've got something very different: a course that requires you to forfeit a chunk of your previous math knowledge and start again. If you're taking Linear Algebra, you've probably already worked with vectors and matrices. As it turns out, up to this point, we've been kind of taking our ability to work with these constructs for granted. All of the foundations need to be mathematically built from the ground up in an n-dimensional space. The benefit of this is that after you learn Linear Algebra, you'll now have a powerful tool on your belt that will allow you to work with any arbitrary n-dimensional space. Doing 3-D rendering? Choose a three dimensional space. Animating? Four dimensional space. Analyzing the costs of doing business and the profit margins of a company you randomly got an internship for? Choose a dimensional space equal to the number of variables you have. It's powerful stuff. But it's not easy. There is an immense amount of vocabulary needed to tackle this course, and some versions of this course are very proof heavy. I've been tutoring Linear Algebra since I took it in 2008 and I have four years' experience as a full time tutor. Please consider me a strong candidate to help you with this course.


Regents

The Regents are standardized tests given in the state of New York in an effort to accurately compare students across many different school districts. A certain number of passed Regents are necessary in order to graduate high school, and the test grades can be submitted to many New York colleges and universities in tandem with your student's college application. I can tutor the Regents (and common core regents) for the following subjects: Algebra I, Geometry, Algebra II, Chemistry, and Physics. I have four years' experience as a full time tutor and I have become well versed in standardized tests like these. Please consider me as a serious candidate to aid your student in these exams.


TAKS

The TAKS exam is very similar to the upper level ISEE exam. It too consists of verbal and mathematical sections. The math sections also include information about learning sequences. The verbal reasoning section is about half straight definitions, and the other half are sentence completion. It is important in the sentence completion portion to find the important word in the sentence. For example: "ALTHOUGH Daniel is an excellent math student, his recent test scores in Calculus were ________." with Although being the important word instructing the student to choose an adjective which describe not being an excellent math student. The reading comprehension section is difficult to tutor for, and it is really helpful for students to read the newspaper in order to get used to reading about topics that they do not know well. This will help them practice their ability to analyze the information given in the article. It is also very helpful to look at the specific words that are used in the passage when asked a question about it. The question may ask for what word best describes a sentence from the selection. Commonly, the previous sentence introducing the sentence in question will include a word that is a synonym for the correct answer. The Mathematics section contain common math subjects: fraction simplification, calculating percentages, converting percentages to decimals, probability, converting ratios, laws about exponents and negative exponents, factoring, inequalities, summation of the sides of a triangle leading to information about the length of the third side, areas, circumferences, volumes, and even a bit about imaginary numbers and roots of an equation. Each topic can be prepared for if it is identified which area the student needs most help with and then sufficient enough time is given in order to learn the topics.


Common Core

Politics aside, Common Core is now the accepted curriculum in the State of New York. The transition has involved significant changes to high school Algebra I, Algebra II & Trigonometry, and Geometry courses. Algebra I students are expected to be able to explain facets of their equations like the slope and y-intercept of a line in the context of a problem. Algebra II / Trigonometry students face major changes including a more rigorous introduction to statistics including discussions about sample means, which many students find especially confusing. Geometry students face more elaborate word questions and vocabulary. I have experience teaching many students over several years in both the previous New York Regents curriculum and the new Common Core standards and I can help explain topics that are not always well understood (be it by the teacher or the student).
