I tell EVERYONE about Clutch prep! I was able to make an A in OCHEM with clutch prep and am using them again for BIOCHEM. I just completed my first test in BIOCHEM and made a 96 so off to a really great start due to clutch prep! The videos are short so you can watch as many or as little as you want within a sitting and it's easy to go back and review concepts that you need a little extra time with (instead of having to dig through hour long videos for the one topic you are looking for). It is also super beneficial for people with ADD/ADHD becuase the videos are short and engaging. Once you feel yourself mentally drifting away from the videos, you can easily stop and come back to it later! It's the BEST teacher I've encountered! They also let you watch a couple of videos for free before you commit, so try them out! What have you got to lose?
