Clutch has helped me so much through my science courses.. personally, I am not one who follows along with lecture too well when concepts get complex and confusing. I like that I can go on Clutch and watch a video that easily describes the material that was discussed in lecture, and I like that I am able to apply it to the information from lecture. I also like that Clutch offers a lot of practice problems & videos providing worked out solutions (step-by-step) and are able to answer any questions about the material that you may have. You should use Clutch if you find yourself falling behind in lecture, or to even want to show up to lecture with some sort of knowledge on the information you are about to learn... it has been such a help to me & my grades.
