Students Who Passed With InstantCert

My son took the biology CLEP and got a 71, and Instantcert was a great help. The flash cards helped, but the forums were what really helped us to find resources and make a study plan. I'm thankful for this great resource. It was well worth the investment!

InstantCert has been a lifesaver for me and my siblings! I was able to pass the biology and American history CLEP exams because of it and I began with very little prior knowledge (especially about biology). I recommended it to my siblings after my success and they had similar experiences for their CLEP exams. You won't regret it!
Julie Sommer
The prep materials were so helpful! I used the flashcards to study for the biology and US History II CLEP tests and passed both the first time. The feedback from other users who took the test was incredibly useful as well. I would highly recommend InstantCert for anyone needing to take a CLEP.
