Knowledgeable STEM Tutor/Part time HS Teacher with Master's Degrees

My name is William, a retired engineer and now a STEM tutor and part time Math/Science high school teacher. I have a BS in chemical engineering and a master's in environmental/management engineering. I also have over 10 years of actual classroom teaching experience in Chemistry Math/Algebra, Calculus, Geometry/Trigonometry, environmental waste management and chemical engineering. My recent private tutoring work involved some of my family members, relatives, and friends in their high school/co... [more]

I have 3 certificates of proficiency from the Los Angeles Unified School District's (LAUSD) Technical Education Department's QuickBooks Accounting course in early 2007 - one in computerized accounting, one in advanced computerized accounting (QuickBooks), and one in Business Math. Because of this QuickBooks proficiency certificate, I was able to work as Part Time Bookkeeper at a construction company in Los Angeles from November 2007 up to the present. I also have another part time bookkeeping job that uses QuickBooks accounting at a small service business since 2010. Hence, I am confident, I can teach QuickBooks accounting to my students. To update my 1989 MBA degree, I have successfully taken and passed (A's) 21 units in College Accounting classes including a 3-unit course in QuickBooks Accounting. While in college, I had the chance to tutor some of the students in accounting and the use/navigation of ProQuickBooks accounting software.


I have passed the CBEST in 2003 on my first and only attempt. I only had a limited amount of time preparing or reviewing for this test as I was only a temporary visitor in 2003 in Los Angeles. Nonetheless, I did well in both Reading and Writing (essays) but I got a very high rating in Numerical Ability (Mathematics) which was expected due to my engineering background. Since then, I have helped a number of students who attempted to take CBEST. Majority of them also passed the test at their first attempt. Only very few needed a second attempt to improve their scores. I have also used this CBEST experience in helping some community college students who are struggling in their English writing and composition courses and even in writing some of their papers in other courses like Philosophy, Political Science, and History. I am generally a good test taker, and I always take any test in which I qualify.


In addition to my chemical engineering education, I have studied for a year the pharmacy technician course at LAUSD - Technical Education Division in 2006. Subsequently, I took the Pharmacy Technician Certification Board (PTCB) in Nov 2006 and passed it easily (89%), in which I got an excellent score in calculations/drug dosage section. I have also taken a semester's course in Pharmacology at a community college in 2011. I have also tutored recently my daughter and her friends who were taking a Pharmacy Technician course. My daughter also passed the PTCB test with high marks. I am very good at calculations and this is where my students benefit the most. I can also do pharmaceutical chemistry. All of them were successful. I shall be glad to send you a copy of my PTCB rating/certificate if necessary.


I have the skills and experience to tutor students in this discipline (TEAS) because I myself have demonstrated passing this test at one try in July 2010 with an above average passing score of 88.8% and a national percentile rank of 97%. Of particular interest, I did very well in Math (99%), Science(98%), English (90%), and Reading (66%). Should you deem it necessary, I can forward you a copy of my TEAS results. I have privately coached a relative and 2 friends and provided them tips about taking TEAS test. They were happy and they passed it on their first attempt. I attributed my success to this test to my strong background in the sciences and math. My tutoring experience in math and the sciences plus my 10 years classroom teaching experience are added advantages for me in tutoring students on TEAS.

Chemical Engineering

I have been a chemical engineer for around 25 years now. I obtained my bachelor's degree (evaluated as U.S. equivalent) from a foreign country (magna cum laude). I took and passed the chemical engineer's licensing board where I ranked one of top 10 successful examinees. Soon after that I worked as chemical engineer in the chemical industry, and at the same time had a part time college teaching work in chemical engineering, chemistry, algebra, geometry and engineering economics. Having gone through the rigorous steps in the licensing processes, I also helped some of my students prepare for the licensing examinations. Through these years of teaching, I have seen a number of my former college students went on to finish college, got their degrees, and succeed professionally. I take pride in being part of their success. With my students early success in their academic goals, I found teaching just as rewarding and fulfilling as with actual engineering practice. And since then, I always made sure I had a part time teaching job while working in industry. Due to my burning desire for advancement, I went on to pursue graduate studies in management and later in environmental engineering. Both of these additional degrees complement and supplement my interests in chemical engineering. Soon after that, I then went on to serve as part time graduate school lecturer for 7 years on selected topics in chemical, environmental, and wastewater engineering.
