freepracticeSAT.com and The College Panda's SAT Math Book

By Dr. Daniel Brink, Ph.D. in Mathematics Education, 32 years teaching math · October 28, 2026

The College Panda's SAT Math, by Nielson Phu, has been a favorite of students aiming for top math scores for years. The third edition is updated for the digital SAT. If you have it on your desk, you have a good book. This page is about how to get the most out of it, and where my site fits.

Full disclosure: I built freepracticeSAT.com. The book details come from The College Panda's website, checked on October 28, 2026.

What the book is good at

As the author describes it, the book explains every math concept the SAT tests, gives many examples of how each question type can show up, and has more than 500 practice questions grouped by topic, with explanations. It is written for students who want a very high score, so it does not skip the unusual topics.

A good book has one big advantage over any website: you can sit with it, work through a chapter slowly, and write in the margins. Many students learn best that way.

The question a book can't answer

A book can't tell you which chapters you need. Most students who buy a big prep book start at chapter one and slow down somewhere in the middle. By the time the test comes, they have worked hard on topics they already knew and never reached the ones that were costing them points.

There is a second, quieter problem. Practice questions grouped by topic tell you what kind of question is coming. On the real test you have to recognize it yourself, mixed in with everything else. Topic practice and mixed full-length practice both matter.

What my site tells you

On freepracticeSAT.com you take full-length math tests, as many as you want, in the same format as the real math section. After each test you see the mistake behind each wrong answer, and the basic skills underneath, from the 280 skills I call the DNA of SAT math questions.

Here is a small example of the difference that makes:

The wrong answer $1$ comes from subtracting $2$ and then dividing by $3$, instead of multiplying by $3$. If a student makes that same move in several questions, the chapter to read is not one SAT topic. It is the one on solving equations, and in particular undoing division. My site points that out after the test. With that list in hand, you can open the book to the right chapters.

Using the book and the site together

1. Take a free full-length math test on my site.
2. Look at the mistakes and basic skills that came up most. Pick the top three.
3. Find the matching chapters in the book. Read the explanations, then do the practice questions for those chapters on paper.
4. Take another test on my site about a week later. If those mistakes are gone or rarer, pick the next three. If not, stay with them.
5. Keep the official Bluebook tests for checkpoints and the last week.

This way the book is used where it helps you most, instead of from front to back.

If your math score is below 600

The College Panda book is written for students going for a very high score, and it moves quickly. For a student around 450 to 550, I usually see the trouble starting earlier, in skills from middle school and Algebra 1: fractions, negative numbers, distributing, solving simple equations. Those are not SAT chapters; the book assumes you already have them.

If that sounds like you, start with my free Foundations course. It is 275 quick checks over four days that find and fix exactly those skills. Then the book will make a lot more sense.

Work on paper, whichever you use

One habit matters more than the book or the website: write your work down. Students who do SAT math in their heads, or straight into the calculator, make the same small slips again and again and never see where. When the work is on paper, you can look back and find the exact line where it went wrong. That is true for book problems, for my tests and for the real SAT.
