I barely passed Calculus II, I got 50 in the whole course after finals and I had 56 before finals. The class avg was around a high D but I can't remember exactly now but that's besides the point. Calculus II at my college was integral calculus with some application of integrals(volume, surface area). I need Calculus III, and I don't really want to retake Calculus II. I'm ready to put more work into my courses now so is there any advice on what I should do? I thought I should review the entire Calculus II course on my own but that may be impossible? I don't know I need some sound advice any takers?
