    "InstantCert has great flash cards and was the only site I found with precalculus flash cards. I took seven Clep tests while using Instantcert, and I was able to pass all of them. When I had trouble with my subscription, they were very helpful and responsive. I would definitely recommend you use this site!"

    "Great purchase. Would not have passed the CLEP exam without them. There were so many questions that were not word for word from the flashcards, but they were rephrased versions of the flashcards. Could not recommend them enough!"

    "I have used instant cert sporadically for my Clep/Dsst study material and have yet to fail one. My transcript probably has as many in school credits as CLEPS/DSST. The Flashcards are Great and the user forums are super insightful. Plus starting and stopping is as easy as an email and I’ve done it multiple times with easy. Can’t recommend enough"

    "I used InstantCert to prepare for a CLEP exam that I had very little knowledge of the subject matter. The flashcards were invaluable, and I was able to quickly get acclimated with the subject matter and test topics. Going through the flashcards, helped me ascertain the areas that I needed to focus a bit more on. This was a great help!"

    "I passed the first time. It was a good extra resource. I also use the Modern College course, along with American government textbook recommended by Modern College as a reference."

    "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. If you’re taking multiple exams, go ahead and buy it instead of paying monthly. You won’t regret it!"

    "No doubt the best CLEP/DSST study tool. It’s totally worth the subscription because I literally have passed every exam I’ve taken because of the study questions they provide. Forget about buying or checking out all the study books that you will barely use. InstantCert makes studying so convenient and they don’t skimp on the knowledge. Do yourself a favor, try it out and you will see the results for yourself guaranteed."

    "It really did help! Many of the questions in the flash cards were similar to the questions on the exam, and it really helped that they gave me an abundance of information to cover. I wouldn't have passed without using instant cert! I highly recommend them!"

    "Instantcert definitely helped me pass two DSST exams: Money & Banking, and Astronomy. M&B was a very challenging test, and the flashcards for that course need to be updated with more current and relevant information. One improvement I would like to see is to reset individual question progress if you get one wrong that you previously mastered. I highly recommend you use this program to study for any CLEP or DSST exam."

    "I thought I was done with my Computer Science degree and after my graduation evaluation I was 1 credit short for degree completion. I studied the flash cards for 12 hours, went to take the exam, and passed with flying colors. Highly recommended and well worth $20."

    "I wish I had found this tool much sooner in my studies for CLEP History of the US II. After reading all the recommended books and watching all the videos, the material just wouldn’t stick. InstantCert worked for me!! 10/10 recommend!! Absolutely worth the $20 fee."
