Hello everyone thank you for all the tips! Yes chem is a major requirement and it is a pre req for gen chem 2 and organic chemistry (there are no alternative forms these courses unless you do honors level).
I emailed my professor and he gave me study advice. He said there is a chance I could still pass once the curve is implemented, but to not to depend on it and work hard for my final exam.
I have attended review sessions and office hours, but not consistently as I have other heavy classes I go to office hours to as well. Currently I am struggling in my other classes (classical physics and calc 4). It feels like an overwhelming slope, but if I manage to pass my classes with a C- and above (the minimum is C- to go to the next course), I will be able to take only 14 units compared to the 18 units I am currently taking.
