Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

ACT Math

Topics covered include: basic algebra, with percentages, sequences and series (arithmetic and geometric), factorization, algebraic division; advanced algebra, with exponents, logarithms, geometry, trigonometry, graphs, rational expressions, permutations and combinations; intermediate and advanced math, with measurements, units, roots of equations.

Bible Studies

I graduated from Moody Bible Institute after 3 years of study, and can teach Bible Studies.

I can teach Basic Theology, Hermeneutics, New Testament, Eschatology.


I have programmed with C on many projects when I worked for Xerox Corporation as a Research Engineer. I am willing to take a test to prove my skills and experience.


Topics covered include
(a) limits and continuity, derivatives of algebraic, trigonometric, exponential, logarithmic, hyperbolic functions; implicit derivatives.
(b) Riemann integrals, integration by substitution, integration by parts, use of partial functions; multiple integrals; numerical integration with trapezoidal and simpson's rules.
(c) only if required: integral transforms (Laplace, Fourier, Hankel).

Civil Engineering

I have a Ph.D. (Eng. Sc.D.) in Engineering Science and MS in Mechanical Engineering (both from Columbia University). I took a test on Elance (now Upwork) in Civil engineering and ranked in the top 5%.

Computer Programming

I know these programming languages: Java, Javascript, Fortran, Visual Basic with Excel, Matlab, HTML, DOS scrpting, Bourne shell, C shell.
I should be able to help others with programming.

Differential Equations

I can teach ODES (1st and 2nd order), PDEs with separation of variables or with integral transforms.
I can also solve ODEs and PDEs numerically with Runge-Kutta and finite differences (explicit or implicit).

Elementary (K-6th)

I have created K-6 instructional materials, questions and answers for two states in the USA as a freelance consultant. I can provide samples of my lessons as confirmation.

General Computer

I can teach general computer skills. This includes basic computer architecture and programming in C, Java, fortran.

I can also teach Office skills and HTML, JavaScript. With a little bit of review, I can teach PHP and SQL.

Linear Algebra

I can teach linear algebra. I taught the subject at Rochester Institute of Technology in the MEch. Engineering department.


I taught Matlab for 5 years at RIT as part of Numerical Analysis. I can teach basic Matlab, and reasonable amount of the graphing package.

Mechanical Engineering

My formal training is in mechanical engineering, and I hold BSME (Imperial College, England) and MSME, Ph.D. (Columbia University, NY). I can help mechanical engineering students in these courses: statics, dynamics, stress analysis, heat transfer, solid mechanics, finite elements, numerical methods.


I created an online course in PreCalculus for a community college in Texas.


I have been tutoring students for the SAT exam with good success, and I can provide tutoring for the PSAT as well.


I am already tutoring trigonometry for the Regents exam. I can also teach geometry, algebra, math A, math B, and physics. With a little bit of review, I can also teach earth sciences.

SAT Math

A student who scored too low in SAT math (twice) could not gain a college scholarship. After I tutored him for 2 months, he passed well and got a scholarship to SUNY Fredonia.


I have been tutoring students for the SAT for WyzAnt with good success, and I should be able to help students prepare for the SSAT exam as well.


I have been tutoring students for the Regents and SAT exams with good success, I should have no difficulty tutoring students for the TEAS exams as well.


I have tutored students in trigonometry for ACT, SAT, GRE and in college math.


I can help beginning and intermediate computer science students or engineering students to become familiar with the Unix (or Linux) Operating Systems. I can teach Bourne and C shell scripting and how to create C-code in the unix environment. I have over 7 years experience working in the Unix environment.

Visual Basic

I have worked on projects in which I wrote Visual Basic code to drive the cells in a Microsoft Excel spreadsheet. However, I have not written standalone Visual Basic programs.
I can provide a sample of my work to demonstrate my skills and experience.
