Hi all, Im not trying to brag but I recently got an A- for my first semester of calculus however the second semester has got me worried. My friend who is a semester ahead of me recently flunked out of the second semester of calculus, and as far as I know, he was an A calculus student. I know every college uses different books, but the one we are using takes us three semesters to get through. The second semester is all about finding volumes, techniques of integration, arc lenths, differential equations,sequences, convergence, ect. Is it really that hard or am I worried for nothing? I consider myself a math person and the first semester was pretty easy for me. Any suggestions?
