How hard is calculus one (1151)?

So far I’ve thought that calculus one has been easy, I did very well on all the quizzes and homework then came exam time and somehow got a 64%. Is it impossibly for me to bounce back from this and get a B the least ? Everyone says that the next exam is much harder and I’m very nervous besides that I have Chem 2 (1220) , and A difficult biology 1 course .

From what I have seen, Calc one and Chem one are extremely difficult classes at Osu that take a lot of time. I can not answer your question but I hope everything works out.
