About Joshua

Hi all,

My name is Josh. Thank you for taking the time to consider me as a tutor. I am a current graduate student in applied math and an instructor at Cal Poly Pomona. I would recommend reading some of my students' reviews to get a better idea of who I am as a tutor.

I have been tutoring and teaching full time for the 7 years. I enjoy helping others out and seeing them get to the "Aha moment!" Math is my main specialty for tutoring; I can tutor up to Calculus and Statistics and some additional topics, including discrete math, linear algebra, numerical methods and optimization. In addition to Math classes, I tutor a lot of Physics.

In addition to normal school subjects, I am an expert for the SAT/ACT Math section. Besides working on my own with students from WyzAnt, I am an instructor at a well known and reputable private SAT academy. I can guarantee you will see an improvement on the Math score; my students commonly see improvements of 100-150 points! Math section alone. In addition to SAT/ACT Math, I can help with ACT, GRE, GMAT, ASVAB, CBEST, SSAT and ISEE math sections. For the ASVAB, ISEE and SSAT I can tutor all sections of the test.

Feel free to contact me and good luck on your search for a tutor.

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

The ACT math section is a little different test than the SAT. While working on the ACT more content problems might come up than on the SAT. Also, a knowledge of trig is needed for the ACT and not the SAT. A slightly different strategy might be needed for ACT.

Algebra 1

Algebra 1 classes represent the core of algebra, these topics will be seen through almost all classes up through calculus. It is necessary to develop a solid foundation of algebra principles here so that later classes will not present problems. Moving up from prealgebra I make sure to focus on the properties of algebra, how to solve equations and more complex problems.

Algebra 2

Algebra II is a return to an algebra based class, even though it usually follows geometry. Most students need a refresher on the more complex properties of algebra found in previous classes. Also, this is the first time we see more interesting topics such as conic sections, logarithms, trig and others. By now it is expected to have solid algebra techniques developed in algebra I, which is where a lot of students need help.


In addition to SAT, ACT, GMAT and other test prep tutoring, I also tutor for the CBEST. The CBEST covers algebra, geometry and a lot of standard arithmetic word problems. I focus on how to approach word problems when studying for this test and others like it.

Elementary Math

As students move through their math studies, a lot of material is forgotten or just not used a lot. Going over the basics again, like fractions, decimals and percents can play a large part in success for algebra and beyond. If a student is seeing this material for the first time I try and make sure that they feel comfortable and natural with topics like fractions.


As geometry is commonly taken after algebra 1, it is a large deviation from previous topics. Because of this students are commonly confused at the beginning and might not recover well. The idea of a conceptual and non-algebraic proof is somewhere I see a lot of students go wrong. When working with geometry definitions, theorems and postulates play a much larger role than in algebra.

Linear Algebra

I have taken some upper level linear algebra classes while at MIT. Also, I took some application specific classes for subjects such as linear programming. I have looked at both abstract classes and applications such as above.


When tutoring pre-algebra I try and focus on the different skills needed to excel in algebra. I notice a lot of students need help in topics such as order of operations, using fractions, and the coordinate system. This is class might be the first introduction to variables/unknowns and I try and make sure students are not afraid of these topics.

SAT Math

The PSAT/SAT is a test not just of specific math topics, but an overall knowledge of math expected from High School students. Practicing word problems in addition to "normal" math problems is usually needed to see improved scores. Better testing strategies can help improve scores as well.


Most statistics classes are a combination of probability and then statistics. I try and focus on some of the common themes, such as finding z-scores and how that relates to different problems. Once that is understood, confidence intervals and hypothesis testing becomes more doable. I tutor AP stats, college stats and some applications in management or business classes.

The Master of Mathematical Knowledge! — I couldn't have passed my Stats final and class at Mt. Sac without Joshua. He knows his stuff, as I stated in the title, he is the master of any mathematical anything. Joshua helped me a lot with Stat; Math is not my subject, I've usually repeated all math courses during my time at Mt Sac. I often had difficulty in understanding and learning math; but with the help of Joshua knowledge, patience an ...
