There’s ONE single skill you have to master if you want to ace the CBEST® Math test: Reading.
Are you thinking that we are mistaken? Think again. Reading is crucial for solving all the problems you’ll face during the Math Section of the CBEST® Test, because all the questions will be given to you in words, not numbers. Reading skills are also important when studying for the test, since you need to understand the fundamental concepts of math if you want to succeed.
That’s why we have plenty of reading material for you and it’s all FREE. You can read 6 pages of preparatory material here:

Or, if you are in the mood for light reading, you can check the following formula chart, which has the essential content you need to know before the test. Also use these when accessing our practice questions and flashcards for this test.
