Fall 2019 - Silkworth is currently my favorite professor in the biochemistry department. Between 153A and 153C, I would say that I enjoyed 153B the most. However, there is SOOOOO much material that's taught in this course. It literally takes the central dogma (DNA --> RNA ---> Proteins) and tells you EVERYTHING about it. The trick to doing well in this course is very simple: Answer all the "what you should know" questions slides in the powerpoint. Do that, and ur pretty much golden for the exams. you don't need to attend any office hours (I didn't even once) or redo the clicker questions. And the best way to answer those "what you should know" questions is to record each lecture on your phone. After class, re-listen to the lectures, and use the recordings to answer the "what you should know" questions. I knew from previous students that this course was going to be hard, so I prepared myself. Going to tutorial also helps as well, cause silkworth dumbs the concepts down in tutorial. Make sure not to lose points over dumb things, like not attending discussion, or not taking the CCLE quizzes seriously (the answers to the CCLE quizzes are from lecture btw), or not doing the clickers. Don't think you can study all the material for this class 2 days before the exam. It ain't happening. Study the slides a bit each day (literally no more than 1 hour), and you will be fine. The average for both midterms was around 75%; for the exams, you will definitely need the whole time length, so be ready in that regard. I'm pretty sure this class is curved to having the average be a B/B+, so don't worry too much about it. Good luck to you all
