# SAT Math: Focus on Quadratics & Parabolas

This book will be the first in a series that addresses the topics that appear most frequently in the Math section of the New SAT. You’ll get a chance to review the most important concepts of quadratic equations and the graphs of parabolas. Then you’ll apply what you know to 25 problems — some done without your calculator and some with, just as it is on test day. Each problem comes with a full explanation of how to arrive at the correct answer.

We’d like to help as many students as possible achieve success on the SAT, so we’ve made the price of this volume just \$0.99.

# New Book: ACT Math Diagnostic Tests

This week we’ve published a new book: ACT Math Diagnostic Tests. Hopefully you’ll find this book useful as you prepare for the ACT.

Perhaps you’re trying to decide which test you’re going to take. Will it be the ACT or the SAT? This book will give you an idea of the kinds of  problems you’re likely to encounter on test day. The math of the ACT includes topics you learned in middle school, like averages and proportions. You’ll also see problems from Algebra and Geometry as well as the functions you learned about in Algebra 2. Finally, each test contains a few problems from Trigonometry.

If you’ve already decided that the ACT is the test for you, this book will help you pinpoint your strengths and weaknesses. Each of the six tests in the book contains twenty problems. By the time you finish the diagnostic tests, you’ll have done 120 problems, the equivalent of two full ACT Math tests. You’ll have done this without using up any of the tests in The Real ACT Prep Guide.

The paperback version is available for \$12.95 on Amazon. In addition, the Kindle version can be downloaded for \$4.99. To preview the book or make a purchase, just click on the book cover above.

# Advanced Trigonometry Print Edition Now Available

Last month, we launched the Kindle edition of  Advanced Trigonometry: Math for the ACT. Now you can order the book in paperback as well via Amazon.

With the print edition, you get the added benefit of being able to write in the book, making your own notes and marking up the diagrams as you work your way through the problems.

This book is the first in our series on ACT Math. The next volume, Algrebra: Math for the ACT will be available in the coming months.

To preview the contents of the book or to make a purchase, simply click on the book cover to the left.

# Print Version Now Available

After successfully launching the Kindle version of the “SAT Math Challenge Problem Workbook” three weeks ago, we got to work on the print version of the book.

You can now purchase the paperback version via Amazon. It has the same content as the Kindle version but with the added benefit that you can write in it, marking up the diagrams as you work on the Geometry problems (and we all know you should definitely be marking up the diagrams on the geometry problems!), writing and solving your own equations right there next to the problems, and making notes as you go along.
