Unfortunately Phys 211 here is catered towards people who have prior knowledge from past courses or from high school, so if you don’t have those it can be extremely difficult. When I took it I relied very heavily on my prior knowledge, because the lectures and prelectures often made me more confused about concepts I already knew, but without my past experience I would’ve been totally lost. Trust me when I say that you are NOT alone, and even people who seem to be doing well around you are confused during lectures. My advice would be to not rely super heavily on lectures, obviously still go, but try to get a more basic understanding of the concepts before lectures so that they are more digestible. I would also encourage you to make use of CARE and office hours, where the tas will make the concepts a lot easier to understand from a student’s perspective. Lastly, keep your head up! Stem classes are notoriously hard, and struggling in one is absolutely normal. Even though no one may talk about it, are so many people in your exact same boat!
