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 would throw at me. After barely making it through my midterms, I decided I couldn't go on anymore without getting some help. At my first session with Andy I immediately knew that he was going to be the one to save me from this pit I was in. We started off slowly with going over some problems I'd missed on my midterms, then after that he'd help me with my homework and extra credit problems. I struggled to learn from basic algebra concepts to abstract calculus problems, but Andy was very patient with me and gave me time to absorb the information calmly. He is very knowledgeable and really knows how to teach. He actually has a real teaching experience--he used to be a high school Math teacher. Whenever we were going through a problem and I'd have a chain of questions, it was amazing to see him explain as if he anticipated all these questions that would pop up in my head. He's talented in explaining abstract math problems in a simple and easy to understand words and is brilliant in making connection between the subjects being learned and the ones that we learnt before. I had so much fun during our sessions because there was so many "Ah-ha!" and light bulb moments. Particularly when I grasped the concept of the triple integrals after a long difficulty trying to understand them, it was exhilarating! I never had so much fun learning math as much as this!

I could tell that Andy really loves the subject especially when we're solving tricky extra credit problems (I'm telling you those were real, I mean real brain stretchers) his eyes would light up and boy, the way he solved through those problems as he explained them to me, I'm like speechless! He is extremely smart! Plus, there is no better person to learn from than the person who loves what they're teaching.

Some people may laugh at me for fussing over Business Calculus because it's "watered down", but hey it's still all calculus 1,2,3 combined and the class I took was so difficult that half the class dropped out. If it wasn't for Andy I would've been one of those poor souls.

Instead here I am, happy with my solid A, writing up this long review for him because I don't know how else to thank him!

So to everyone struggling with any levels of Math out there! Take my word, Andy is no doubt a "Math magician" so give yourself a chance to see his magic at work!

Andy is an extremely knowledgeable and patient tutor. Andy is committed and goes above and beyond to ensure your child understands. He is one that you can count on to encourage your child for ultimate success.

According to my son, It clicked once Andy started explaining how to work each problem. He is very knowledgeable and patient and I will have him tutor my son again.

Just with one hour of tutoring, Andy helped my son understand Stats a lot more. My son then felt comfortable and less frustrated, we was able to complete his homework without a problem.

The main objective in this lesson was with Related Rates topic, in which our son learned how to find the unknown rate of a particular quantity such as how fast the height of the water rising at a particular instance.

I was a bit confused on some concepts in Calculus 3, but Andy really helped me understand them! He's very knowledgeable and understanding. I highly recommend him!

My son Max loves working with Andy. He is a great tutor. Andy does a fine job in explaining the concepts to my son. He is also very patient , and helps my son in his areas of weakness.

Andy knew the material, did well in explaining things, giving directions, and Max was able to finish his assignments on his own, which was the objective. Thank you Andy!

Andy has been a wonderful pre-calculus tutor for my daughter. He is very knowledgeable and patient and allows her the time to figure out her mistakes rather than immediately pointing out what she may be doing wrong as they work through the material. I believe this is very important as the tutor is not with her during class and exams. Andy has also been flexible with scheduling sessions around sports practices and games - I very much appreciate this!

Andy helped with breaking down the problems so I could understand. He is vey knowledgeable on the subject and I felt reassured that everything was going to be ok.

Andy took the the time to explain why you did the problems the way you do not just the steps

Andy is the best tutor I have had. He is very patient and is able to quickly adapt to my needs. I would not be passing my algebra class if I did not have him as my tutor.

He relates very well with my daughter and understands her questions and is able to answer them in a way she understands.

Andy tutored my son in calculus and by the end of the session, he felt much more confident about the subject. In addition, Andy was very knowledgeable and opened up new methods my son did not know about in his studying. He is a great tutor and a pleasure to work with.

Andy has been helping my son with his junior level math course - he has helped my son grasp difficult concepts and has made himself available on short notice. My son has really flourished with his tutoring. Thank you Andy!!

Andy tutored my daughter in precalculus. She felt very comfortable with him and was extremely happy with the results. She is feeling quite confident about her upcoming test! Andy was also very easy to get in touch with. I spoke with him within two hours of my inquiry and was able to set up an appointment right away.

Andy is bringing such peace to our daughter. All she says after each lesson is "He makes it so simple mom"! Those words are priceless and well worth the tutoring cost and more. Thank you Andy!

My son would be failing his university calculus class if it wasn't for Andy. He wasn't learning anything from the teacher and was getting so far behind. He needed help immediately! We contacted Andy and he came over over a few hours later. For the first time, my son was getting the concepts. Andy has been very patient and has been wonderful at working with my son's schedule. I would recommend him to anyone.

Andy is just a very knowledgeable tutor who matches the needs of the student. He is flexible in assuring he arranges the time you need. He is creative in addressing problems so that the student grasps the material. I highly recommend him.

Andy was great! He was patient and able to explain the concepts very well! He had great tips that were easy to remember and understand. I had a 2 hour session with him prior to my precalculus exam and it was very helpful!

Andy helped me go over every problem and concept. I really understand the math better now, and we got a lot of work done in an hour. He is patient and good at explaining!

My daughter is an Algebra 2 student. She finds Andy L very helpful in guiding her through Algebra 2. He is very good about finding time to help my daughter and has a nice and pleasant personality. We are very happy with Andy L as our Algebra 2 tutor.

Thank you Mr. Andy for helping me to understand my math problems now. You are an excellent tutor. I am very thankful to you.

Andy did a fine job. He gave an overview of the material and was patient and knowledgeable. He continues to give her the support and expertise she needs.

Approved subjects are in **bold**.

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 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 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 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.

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 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.
