College Math Clep, Speedyprep questions

Has anyone used speedy prep for college math clep? Did you have success? My concerns are as followed...I've checked out a few practice exams and some of the questions aren't covered in speedy prep. Secondly, the questions and material are wildly different than what is in the rea book. Apologize for brevity, on iPad. Just looking for some thoughts, and maybe a good place for practice tests that will accurately reflect what's on the clep.

Thank you in advance

 

REA is a solid source. For practice tests, try Petersons. It's $20 and you get 3 of them. If you're passing Peterson's >50% you're likely ready.
