Find the Weak Spots, Then Fix Them One by One

More practice tests only raise a score when a student knows exactly why each question went wrong. So we start by finding the weak spots, then fix them one skill at a time.

Official tests first

Students take College Board Bluebook Practice Tests 9, 10, and 11, then study the score analysis. It shows which skills are costing points and which are already solid.

Every miss is coded

Every question in the College Board’s released Question Bank is coded by skill in our system. When students miss a question, they write down its code. That is all it takes to build a precise error log.

Personal practice sets

After about six weeks, the error log shows each student’s patterns clearly. From then on, we assign personalized problem sets that target the skills they miss most.

Practice Works When the Basics Are Solid

The Bluebook tests and the Question Bank are the best SAT practice available, and they work when a student’s foundation is strong. When it is not, more practice only repeats the same mistakes.

Strong foundation

Diagnostic tests, the error log, and targeted Question Bank practice. The work is finding and fixing specific weak skills, usually in a small group.

Gaps in the basics

We rebuild the core ideas first, usually one-on-one, so the student understands why each method works. Then SAT practice starts to pay off.

Which one is right?

Our free practice test and a consultation show where your child is starting from, and which path makes sense.

Two Ways to Learn

SAT Math courses open several times a year. Each course runs for a set number of weeks, such as a 12-week course or a shorter 5-week course, and we add intensives over school breaks.

Small Group Course

Raise your score alongside a few motivated classmates.

For students with a solid foundation. The group works through each skill area together, and each student’s error log shapes the practice they get.

  • Groups of up to 6 students
  • Taught by our director, Chi Ji
  • Personalized practice from each student’s error log

One-on-One Lessons

Built around one student’s foundation and goals.

For students who need to strengthen the basics first, or who want a fully individual plan. Lessons start where your child is and move at their pace.

  • Recommended when the foundation needs work
  • Taught by one of our experienced math teachers
  • The same error log system, for one student
  • Scheduled around your child’s calendar

In person or online

Every course is hybrid: join at our Fullerton center or live on Zoom.

Courses through the year

New courses open during the school year, plus intensives over winter and summer breaks.

Missed a class?

Missed group classes can be made up with the Zoom recording. See our FAQ for details.

What Families Say

In the words of ICMS parents and students.

We are extremely happy with the way Mr Chi is tutoring … Mr Chi is extremely helpful. … I will recommend him to anyone who needs help in Chem AP, SAT Math, and other science classes.

Harish M. · Parent

They don’t just teach formulas, but they make sure students truly understand the concepts. The explanations are always clear, and they take time to answer every question thoroughly. … My daughter not only improved in grades but also developed a much more positive attitude toward math.

J. I. · Parent

From the outset, his teaching environment was welcoming and focused on understanding rather than memorization. … Thanks to his diligent and brilliant teaching, starting from the 5th grade onward, I’ve never worried about math, even as I went into the difficult math AP classes.

Questions Parents Ask

Have a question that is not here? Ask us during your free consultation.

How should my child start preparing for SAT Math?

Start with the College Board’s official Bluebook practice tests, especially Practice Tests 9, 10, and 11. Take each one under real timing, then study the score analysis to see which skills cost points. Practice those skills with the College Board’s released Question Bank. This works well when the basics are solid. If they are not, it is better to strengthen the foundation first.

What is the error log?

Every question in the College Board Question Bank is coded by skill in our system. When students miss a question, they only write down its code. After about six weeks, that data shows each student’s weak points clearly, and we assign personalized problem sets to fix them.

Should my child join a group course or take one-on-one lessons?

Group courses have up to 6 students and work best when the foundation is solid. If your child has gaps in the basics, we recommend one-on-one lessons first. The free consultation helps you decide.

Are classes in person or online?

Both. Our courses are hybrid, so students can join at our Fullerton center or live on Zoom.

How much will my child’s score improve?

It depends on the student. In summer 2026, many of our students went from the high 600s to the high 700s. How far a score rises depends on each student’s effort and consistency.
