Hello Parents and Students!

First and foremost, I frankly thank you for spending the time in surfing or just happen to stumbling onto this site. Whether you are searching for extra assistance in long-term, short-term, or just to brush-up the concepts for an upcoming quiz, test, mid-term, final or standardize tests then you have visited the right place.

My name is Andy, A.K.A the “Math Magician” preferred by most of my high school students because they always amazed and loved the way I translate complex and difficult problems into very simple ones. Both teaching and tutoring have been part of my life for the past sixteen years. I possess a bachelor degree in Mathematics with specialization in Statistics from UCI and over 40 credit units in the master degree in math and teaching credential at CSULB. I also passed both CBEST and CSET exams as requirements for subject competency. I always enjoy every single opportunity when it comes to providing tutoring in my expertise subjects which range from Pre-Algebra up to Differential Equations.

Loosely speaking, I can always be related to many students because I was horrible at math in my first two years of high school. That’s right, I struggled and could never grasp the concepts of solving word problems in Algebra 1 and proving problems in Geometry; for me, I thought it was another language of its own—especially when English was my second language. However, I never gave up on math—I kept my motivation intact and continued to “study math the right way” and my math phobia eventually deleted from my memory ever since I got into college. Since then I excelled in math and it still remains as my strongest and favorite subject. One of my college professors once told me that I was a late bloomer.

Over the course of my teaching and tutoring career, I have carefully observed and formulated three important components that are valuable access and essential to help students and change the way they think about math. I called these components as Right Styles, Right Techniques, and Right Mathology.

• Right Styles: I help students to identify the right learning styles that best fit his or her learning behavior. Sometimes students feel too overwhelm and can’t figure out what, when, where, or how to study. There are styles that don’t necessarily require to study hard but to study smart and efficient especially when studying for assessments such as quizzes and exams.

• Right Techniques: I help students to learn how to identify and apply the right solving techniques to solve certain problems since most, if not all, problems present differently. Show them logical ways to translate mathematical language into plain English or math expressions or equations. It’s just like you have a box of tools but need to select the right ones in order to perform the job right. Hence, if a student possesses a set of solving techniques and know how to use it, then it definitely will boost his or her confidence.

• Right Mathology: This is the most important component of the three. Generally speaking, sometimes students misunderstood certain concepts simply because of the way it was presented or students bent the concepts and interpreted to the way they understand it. Since every concept in math are highly interrelated and it can be considered as the foundation and stepping stones to the next level; therefore, as a mentor, I will play the role of the detective to detect students' weakness in order reinforce the concepts in depth.

My desires are not only to help students get through with their daily homework and to ace the test and forget everything afterward, but to help them develop their critical thinking process by providing concise questions and feedback, challenge them with difficult problems to stimulate their brain to enhance long-term memory, and criticize their mistakes for them to acknowledge and improve upon.

At the end of the day, I believe that a good mentor is comparable to a good doctor with magic hands, sound background, and solid experience in their perspective fields of practice that can diagnose and provide the right treatment on the first or second visits to save the patients' time and money.

Thirty years from now it doesn't matter how much money I have in the bank or what kind of car I drive, what is matter most is how many life I have effected.

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.

Algebra 1

Algebra 1 is great fun – you get to solve puzzles!
You play some computer games by running, jumping or finding secret doors. Well, with Algebra you play with letters, numbers and symbols. And once you learn some of the “tricks”, it becomes a fun challenge to work out how to use your skills in solving each “puzzle”.

Algebra 2

Algebra 2 is really fun, interesting, and challenging because it required the knowledge and skills of algebra 1 and geometry. In fact, I’ve taught both Honors and regular Algebra 2 for a decade and I’d enjoyed every moment of it. I have many short cuts and tricks to help students to memorize formula, know how to graph different types of functions, and solve certain equations as well as solve word problems effectively.


I tutor AP Calculus AB/BC, Business Calculus, and Calculus 1, 2, and 3 with excellence successes rate. Students who took the AP Calculus exam, 80% of them passed with a score of 5 and 20% with a score of 4 or 3.
I tutor college students at CSUF, CSULB, UCI, Fullerton College, San Ana College, Irvine Valley College, Orange Coast College, Golden West College…just to name a few.
In general, I love to figure out math problems, especially calculus problems. I guess because there is always a right answer and there can be many ways of going about getting that answer. Unlike English, an essay can never be perfect, it can never be completed—there is always something more that can be done.
I told my calculus students that math skills are like muscles in your body, if you don’t work out you won’t go anywhere. Therefore, you just practice, practice, and practice in order to do well in calculus.

Differential Equations

Differential Equations is one of the most useful and interesting mathematics classes that I've taken as an undergraduate because begins with some definitions and terminology and mathematical models used in a differential equations course. First-order and higher-order differential equations, along with the methods of solutions and their applications are introduced. Modeling with higher-order, Laplace transform, and systems of linear first-order differential equations are covered. At the end, students learn series solutions of linear equations. Numerical methods are covered throughout the course.

I have been tutoring students from CSUF and Santa Ana College for two semesters and I enjoyed every moment of it.

Discrete Math

I am comfortably tutor students an introductory course in discrete mathematics. The goal of this course is to introduce students to ideas and techniques from discrete mathematics that are widely used in science and engineering. I can teach the students techniques in how to think logically and mathematically and apply these techniques in solving problems. To achieve this goal, students will learn logic and proof, sets, functions, as well as algorithms and mathematical reasoning. Key topics involving relations, graphs, trees, and formal languages and computability are covered in this course.


Geometry was totally a different playing field for me when I first took it in high school because I used to have hard time in grasping the concepts of proofs and know how applied the definitions and theorems.

Geometry is more of a visual subject—requires more abstract thinking in analyzing shapes and figures. But now, after teaching Geometry classes for ten years, I’d really like the subject and I personally think it is easier than Algebra since it doesn’t involve with solving complex equations. Despite the fact that Geometry is not as hard as algebra, I still suggest that students must know the definitions, axioms or postulates, theorems, and formula to in order to do well.

Linear Algebra

Linear Algebra is one of the most useful and interesting mathematics classes that I've taken as an undergraduate because it's involved with vector spaces and linear mappings between such spaces. It includes the study of lines, planes, and subspaces, but is also concerned with properties common to all vector space. In addition, this course is very helpful in preparing for Differential Equation course.

I have been tutoring students from CSUF and Santa Ana College for the past two years and I enjoyed every moment of it.


This class has trained me to be comfortable and competent in using logical tools to analyze and understand arguments and to form my own. In the process of familiarizing myself with these tools, I was able come to a deeper understanding of the process of argumentation itself – recognizing in greater detail the underlying structure of the arguments that bombard us every day and being able to respect and evaluate the various elements that can make those arguments strong or weak.


Many students find algebra to be a very interesting subject. However, some students find algebra to be very difficult. Often the reason for this is that they have not yet mastered the concepts of pre-algebra. This is why it’s so important to for students to learn pre-algebra thoroughly before moving on to higher levels of math. If students start doing various kinds of math problems early in their studies, they are less likely to encounter problems further down the road.

Exponents, arithmetic equations and basic graphing are other primary topics in pre-algebra. These are the pre-algebraic concepts with the widest applications in everyday life. Their applications are almost countless. These concepts of pre- algebra are used in almost every field in business and the sciences. From small-scale business to huge engineering projects, algebra plays a central role in solving problems. If the student wants to have a career in business or the sciences, it’s important that he/she learn pre-algebra as a stepping stone to higher mathematics.


Precalculus prepares students for calculus the same ways as pre-algebra prepares students for Algebra I. While pre-algebra teaches students many different fundamental algebra topics, precalculus does not involve calculus, but explores topic that will be applied in calculus. Precalculus was a fun challenging course that I went through in last year of high school. There are three main components of precalculus that are so vital that I suggest students must know:

1. Know how to represent functions. There are many different ways you can describe a functions, the most popular are algebraic and graphical.

2. Know the basic function library. Knowing the basic properties of common will save you a lot of time in your calculus studies. Basic functions include trigonometry functions, exponential function, polynomials, and many more. Each set of functions has unique properties that make them useful in different ways.

3. Know how to transform functions. Basically this is taking one function and turning it into another through a set of manipulations—shifts, stretches, and compressions.


In general, statistics is fun and interesting, especially an introductory course to statistics because it focuses more on how to gather, organize, and analyze data. The used of algebra is minimal so you don’t need to be a math whiz to take an introductory course in statistics.

I have tutored high school and college students, especially adult students, who returned to school to further advance their career and opportunity—majority of them struggled and found it difficult since they haven’t done math for years.

As your tutor, I will help you understand the underlying theory with step-by-step instruction so that you will always enjoy much greater success if you understand what you are doing, instead of blindly applying mechanical steps in order to obtain an answer that may or may not make sense.


Trigonometry is one of my favorite math concepts due to the fact it has many real-life applications. Trigonometry is really isn’t hard. If it seems hard, then that’s because you were taught in a manner that doesn’t work for you. Different people learn different ways, but teachers sometimes only teach one way, whereas the way you are taught needs to be the way you learn.

There are only three important definitions in trigonometry. Everything else is based on those three. If you can understand these three definitions, you should have no trouble understanding any other part of trig.

The three most important definitions are:
Sine of the angle = opposite/hypotenuse
Cosine of the angle = adjacent/hypotenuse
Tangent of the angle = opposite/hypotenuse

Yes, trigonometry finds itself enmeshed within our world. The three trigonometric functions do more than tell us the ratio of sides of a right triangle; they help tell us about life itself. Keep this in mind next time you run into the sine, cosine, or tangent.

So, I am one of those people who used to breeze through algebra classes by memorizing formulas and doing just enough to pass with an A, then forget everything right after that final test...well, such practice took its toll on me when I took Business Calculus this semester. My weakness from slacking off in algebra started to pull me down along with these new crazy calculus problems my professor wou
