    "My homeschooled high school sophomore passed the US History 1 CLEP with a 70 (out of 80). She says the IC flash cards were a huge help. We’ll definitely use IC for her future CLEP tests."

    "This study guide was easy to navigate and had rationales that were easy to understand! Made passing the American Gov CLEP exam possible in just 3 days of studying. The price was also a selling point for me. Overall very convenient and I am so thankful to have come across InstantCert's study resources for CLEP tests! 100/10 recommend!! (For background, government was NOT my strongest subject!) Extremely pleased!"

    "Definitely a good study source for DSST & CLEP exams. It has a community forum to that is also helpful. I found the study materials to be good enough to prepare you as well. I recommend it, especially for the price."

    "I am totally impressed with InstatntCert! My primary source for studying was the flashcards provided by InstantCert. I ended up passing 5 CLEP tests and 5 DSST tests, 6 of which supplied Upper-Level course credit. The flashcards were my only study source for all but two of the tests. This was a great financial investment and the best possible use of my time."

    "Such a great tool in my studying for my CLEP Exam. The study cards were amazing and made me feel like I retained so much material as well as giving me access to 3 test I felt reflected the exam style questions and format! I passed my exam the first time I took it. I recommend using InstantCert in addition to CLEPstudy guide books or any additional material you are using"

    "Helped me successfully obtain my Associates degree. Their guides are relevant and useful. I know you can find free resources but 20$ a month to essentially guarantee you pass your CLEP seems like a no brainer to me. HIGHLY RECOMMEND!"

    "Prepared me well for the Western Civ I and II Clep. If you dedicate at least 20+ hours you will pass with flying colors! Also be sure to read the background knowledge as well in the flashcards."

    "I felt the practice test questions were much more helpful than the flash cards and should have probably spent more time with those than the flash cards."

    "InstantCert was absolutely a crucial piece of my success in passing the biology CLEP test. Best resource out there!"

    -Annie Musgrove on Nov 8, 2023

    "As far as CLEP test prep sites go, InstantCert is a solid option overall because it packs some interesting utility in case the actual content is not enough on its own. I took CLEP Macro, Algebra, and Biology and found some polarizing results. The flash cards for College Algebra and Biology were cornerstones to my understanding of the content and I was able to score a 71s after 4 weeks with only a handful of videos for clarification and using some test prep software. The same cannot be said for Macroeconomics which suffers from explanations that are insufficient for learning the material and tackling the test questions. However, the saving grace is that the forum they give you access to has anecdotes from test-takers who report their scores, experiences, steps and the resources they used to succeed, so you can quickly find what works and what doesn’t."

    "This is a great resource if you are preparing for CLEP exam. It not only provides more archived tests and flashcards, but also has feed backs that earlier students post, which is a good-to-know before you go on the test."

    "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!"

    -Antoni Aybar on Jun 2, 2023

    "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!"

    "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!"

    "The flash cards helped me pass three CLEP exams. Each flash card contains explanations for the answers, that’s where the learning is."

    "Used mainly this site for my DSST and CLEP and passed them. Was informative and it making get the answer right 3 times helped cement it into my brain a little better"

    "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."
