How was your day?

Worried about failing classes in my first semester because I took it too lightly at the start, feel pretty terrible but I guess its not in my hands since I already wrote two. Trying to keep my mind off being worried and study for calculus but man its hard not to think about it. I mean final for physics is worth 46-51% depending on class participation mark, and if I assume I had at least a 60% average before the test (none of our marks but midterm marks are posted for this class). I would need at least a 40% on the final. Just worried I won't hit that 40%, I think I did but there were definitely a lot of questions I was unsure of and some short answer questions I had no idea how to solve. AAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH.

Really disappointed with myself regarding first semester regardless, but if I pass first semester I know I can fix up my issues second. If I fail a class I'm worried I'll tilt off the face of the earth.
