the only reason I will publicly admit that I've retaken orgo 1 and 2 multiple times ( with other the help of Studyedge and other extra help materials and I'm premed) is because I passed Orgo1 with an A using clutch prep and in my current Orgo 2 class received an 88% on my semester's first exam with ( once again) the help of CP. I actually understand the material and solve practice problems without checking for the solutions and getting them correct. Perhaps my one reservation is that I wished there were videos of labs, but for the most part understanding the concepts from the CP videos combined with my class notes and book notes have helped me in that aspect. Still I would recommend Clutch Prep to anyone who wants As in their coursework. THANK YOU CLUTCH PREP !!!!!
