Hello, I'm feeling a little discouraged lately. I'm taking my second introductory physics course this semester, and although I'm doing excellent with the algebra material, I'm terrible at calculus based physics (our class does both separately, with the calculus being 20% of total grade). If I stay in the major, next semester I'm going to take classical mechanics and thermodynamics and I know for sure those will be entirely calculus based (might be a good thing since I'll be more immersed in the math). So suppose I master the introductory algebra-based physics but do poorly at the calculus stuff, can I still catch up later on? I heard that some physics majors take only the algebra-based physics and they do well later on, is this true? Thanks.
