Biochem II isn't cake, there's a lot of material, especially if your prof wants you to know structures of all the compounds involved the the metabolic processes on top of everything else. But at the same time, iirc its literally just memorization and a tiny bit of conceptual application of basic free energy principles. If you put enough work in to memorize everything you get an A, no thinking required. AKLectures on youtube is helpful
