"I just took the COMPASS test today and tested out of 3 math courses. This site just saved me a fortune in extra tuition!!"

"This was probably the best study tool I could have used for the COMPASS math placement test. I'm not one to ever purchase anything like this, but honestly it was SO worth it. I haven't taken a math class in 3 years and forgot pretty much everything. I passed out of 4 math classes on my COMPASS test because of this program. It was so easy to understand and use. Would recommend to anyone!!"

"The school I want to attend requires a 43 for the math section of the COMPASS test. I tried just winging it the first time and blew it scoring a measly 27. I've used this product for 3 months and re-took the COMPASS test today... My 27 is now a 74!!!!! Thank you so much for all the review!!! This wouldn't be possible without this wonderful COMPASS test prep program!!!!"

"Amazing!!! I graduated high school 15 years ago and had to take the COMPASS math test to go back to college. Used this program and passed out of College Algebra. It explains everything on the COMPASS test so clearly and thoroughly."

"I just wanted to say how much I appreciate what your COMPASS math website has done for me. I'm a returning college student and I haven't taken a math class in 10 years. In high school, I was barely able to pass Algebra 1, so I'm pretty terrified of all things math related. When I took the COMPASS exam, I placed in Elementary Algebra. Then I purchased a subscription and studied my way though your COMPASS prep lessons. Not only did I do better on the test, but I placed directly into my college transfer class! Nothing short of a miracle could have taught me Algebra so quickly. You've saved me semesters, money, and headaches. THANK YOU!"
