About John

So you need help learning Algebra, Trig or Calculus!

I guess the reason you're seeking help is not because you watch “The Big Bang Theory” and have seen strange math equations that were written on their whiteboard, but rather, you are currently enrolled in a math course in your high school or college that appears confusing and ambiguous. I too struggled while taking my required math classes. Between my two college degrees, I had 7 semesters of Calculus / Linear Algebra / Differential Equations. This doesn't include classes in applied math, such as Heat Transfer, Acoustics or Op-Amps, where the math learned was used in the subject course. I opted to repeat two semesters of Calculus while earning my second undergraduate degree to refresh my math skills. My background includes 5 years as a Faculty Assistant in the Math department where I primarily graded homework and quizzes.

I'm not going to say learning higher math is easy - it isn't.

What I realized between grading and tutoring was that students needed help either in strengthening their skills to set up the problem correctly, help towards solving the math correctly, or help reinforcing an earlier math principal which were not clear to the student. Many students needed help in all three areas. What I need to determine for each student is what skills each student has and show the student how to attack math in an orderly fashion. What I will provide to my students is a helping hand to show and explain what is going wrong!

So what can I do for you? Help you with derivatives, anti-derivatives (integrals), differential equations, quadratic equations, polynomials, min/max, limits, volumes, approximations, partial fractions and infinite series, to name a few topics. I can help with Trigonometry and algebra too! I won't do your homework but I will help by starting a solution and guiding you to a successful conclusion.

I have earned degrees in Mechanical Engineering from Rutgers and Electrical Engineering from DeVry. I have 25 years experience in design of Controls and Instrumentation used in industrial equipment. Presently, I'm semi-retired, and enjoy designing circuit boards and writing firmware for micro-controllers.

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.


I worked with Autocad 12 and Autocad 97 for several years while employed as a designer for industrial equipment. I'm familiar with paper/model space, layers, blocks, dimensioning and reference drawings. I periodically used isometric mode as necessary. Presently I have DraftSight (an Autocad clone) on my home computer.


I taught myself C after learning fortran, Basic/basica. I taught myself Borland C on my home computer in the early 90's. I'm a fan of structures and graphic modes. My senior project (at DeVry) involved programming an 8088 computer (in C) to drive a circuit board of my own design. Today, my expertise allows me to drive LCD displays and stepper motors under microcontroller control using C instructions.

Electrical Engineering

I graduated from DeVry University in 1997 with an ASEET. I graduated with a 4.0 GPA. I took courses such as Digital Systems, Op-amps, Microprocessor, in addition to standard fare such as Electronics I and II and AC theory.

I worked as an electronic technician, repairing circuit boards returned by the customers. The repaired boards were certified to NIST standards prior to returning to the customer.


I am well versed in digital logic commands such as "and", "or", "nand" and "nor" gates (and various combinations of the same). Typical chips supporting digital devices include 7400, 7402, etc. What I really liked was the programmable chips such as the 8255 - programmable interface adapter!

I previously completed 2 successive courses in Digital Devices and currently use logical devices to decode digital addresses in computer type circuits.
