I'm struggling in this class and I want to try doing more practice questions instead of reading/notes. Our book only has 3-4 for each chapter and Lippincott's doesn't have too many either. Does anyone know of a good source for practice questions just for biochem? If I sign up for Uworld or one of the usmle qbanks, can I do it by subject and do they give detailed explanations? Really desperate here... thanks!
