For me, his tests were ridiculous. It was like being sucker punched from question to question. I'm not the only one who noticed that either. An advisor wondered if perhaps my prerequisites weren't as strong as they could be, and I've started wondering that as well. So, assuming she had a point, what in your opinion or experience is the best prerequisite to prepare one for Biochemistry? Maybe I can watch some videos or revisit old notes this Summer. The good news is that I have 7-8 months (or maybe just 3-4) to prepare to retake it. And beyond that, assuming anyone had an instructor with tests similar to what I just relayed, how did you ultimately clear that hurdle?
