About Charles

Thank you for your time and interest! I have a bachelor's degree in mathematics from Berkeley and have been a full-time tutor since I graduated from college in 2009. The reason why I have been lucky enough to have been able to work full-time as tutor is that I retain my clients. I work with both high school and college level students.

Since I have a degree in math, I can tutor higher level mathematics courses, like Calculus I, II, II, business Calculus, Linear Algebra, and Differential Equations. You will not find me getting stuck on problems very often. And since I've been tutoring for so long, I have the experience necessary to communicate the concepts effectively. I also tutor other mathematics courses, like Pre-algebra, Algebra I & II, Geometry, and Pre-Cauclus.

My first experience tutoring was at Palomar College in 2006, while I was a student there. I was recruited by one of my professors to work for the school. My tutoring work at Palomar gave me a lot of experience tutoring students studying a variety of topics at a wide range of skill levels. I worked there until I transferred to Berkeley in 2007. After I graduated from Berkeley I immediately began tutoring again, but as a private in-home tutor. I passed the CSET mathematics subtest I & II in May 2010.

My teaching philosophy is simple. Students need to spend time learning their subject, and they need to workout their own homework problems. The tutor's job is to explain the material, do examples, and find holes in students' understanding. Mastery of a subject takes time and hard work. I help students by creating focus, which helps them use their study time efficiently, and by finding errors in students' work which helps stop bad habits from forming. I work with the students' own class material at their own pace. I watch the students work problems and see how they react to instruction and adjust my tutoring style accordingly.

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.

Actuarial Science

I have passed the Society of Actuaries exam P with a score of a 9, which means my performance on the exam was near perfect. Furthermore, I took math 440 at CSUSM, which more or less corresponds with the material on exam P and got a strong A. Lastly, my experience with the fundamentals--statistics and Calculus--makes be very well suited to tutor the material.

Calculus

I majored in math as a student, and took the entire Calculus series, and I received A's in all my classes. So you can rely on the fact that I know the material well. You won't find me spending half the time in your book, or frequently getting stuck on problems. Furthermore, I've been a full-time tutor since I graduated in 2009 and I see Calculus students all the time; usually about a third of my clientele are studying Calculus. That means you can count on me to communicate concepts well.

Differential Equations

I have a degree in math.
I have taken differential equations and received an A in the course.
I have tutored differential equations before (most recently last Spring).

Geometry

Geometry is a source of frustration for many students, because it's not like other math that you see in high school. And everybody has to take it. The good news, at least for you, is that that means qualified tutors, like myself, see Geometry all the time, and know how to tutor it. I usually have two or more Geometry students at any given time, and I've been tutoring since I graduated in 2009. So you can count on me knowing this stuff inside and out, and that I can teach it.

GRE

I've taken the general GRE a total of three times so far, and I've developed study techniques that have proven to be effective. In my most recent attempt at the GRE I scored a 167 on the quantitative section, which put me in about the 95 percentile range. I also have a lot of experience as a math tutor more generally, so you can count on me being able to explain the concepts effectively. As of now, I only tutor the quantitative section.

Linear Algebra

I've taken bother upper and lower division linear algebra, and I have a bachelor's degree in mathematics. Furthermore, I've tutored linear algebra before.

Microsoft Excel

My mathematics background has made well primed to learn Excel, and I frequently use the less sophisticated spreadsheet features. Recently, I decided to "beef-up" on my Excel my taking the Infinite Actuaries' "Technical Skills" course, where I studied Excel's more complicated functionality, e.g. VLookup, VBA, and pivot columns. I may be willing to discount my price, depending on my availability and your location, because I would like to keep my Excel skills fresh.

Precalculus

I'm particularly well suited to tutor precalculus, because precalculus tends to be a more advanced version of all the math you've learned before with an emphasis on the tools you'll need for Calculus plus some trigonometry. I tutor Calculus, trigonometry, and less advanced math classes all the time and I'm good at it. You won't find me getting stuck on problems very often or getting definitions mixed up. All our time will be spent teaching, and I have a lot of experience doing just that.

Trigonometry

This is one of my favorite topics to tutor. I love working with more advanced math class, like Trigonometry. And I see it all the time. For example, in summer 2009 I had two Trigonometry students. You'll find that there are a lot of ways to solve Trig problems, some easier than others. Over the years I've found a lot of the easier techniques to solve the problems, and I've developed intuition about where students tend to struggle.
