What's inside the book? This book contains six diagnostic tests, each of which has twenty problems that you might encounter on the ACT Math test. By the time you complete all six tests, you'll have done a total of 120 problems. That's the equivalent of two full ACT Math tests, and you'll have done them without having used up any of the five full tests in The Real ACT (R) Prep Guide. That's important because you'll want to save those for later on after you've done some prep work. They'll be a valuable tool in helping you figure out how your preparation work is going and where you still need to study more. The distribution of the problems in each test mirrors what you'll see on test day as well. - Pre-Algebra & Elementary Algebra - 40 % - Intermediate Algebra & Coordinate Geometry - 30% - Plane Geometry & Trigonometry - 30% Who will find this book useful? Perhaps you've gotten ahold of this book because you are trying to decide whether to take the ACT or the SAT. You can use these diagnostic tests to get an idea of the math that appears on the ACT. There are problems that address topics you learned in middle school and others from high school math all the way through Pre-Calculus. As you take the tests, you'll begin to get a feel for what kinds of math you'll see on ACT test day. Maybe, however, you've already decided that the ACT is the test for you. If so, you can use these diagnostic tests to determine what your strengths and weaknesses are. Maybe you're really good at the algebra problems, but you need to brush up on geometry. Perhaps you need to review the more advanced trigonometry concepts that appear near the end of the test. As you complete the tests and record your results in the tables at the back of the book, you'll begin to see where you should focus your test preparation.
