I've spent a lot of time soul searching after having some academic "failures" in the previous semesters, and what I found is that often when I'm not studying, it's not because I can't study, but it's because the book we're using is unreadable to me. For example, after sailing through Calculus I with knowledge I gained from highschool, and bombing a test or two in Calculus II due to not reading the text, I returned to Spivak's Calculus (having flirted with it a bit in highschool) and had a religious experience. That read like a novel, and the problems were hard but I enjoyed solving them. Now, I haven't had time to finish the text, but I plan to. However, the forward progression of classes marches on, and now I find myself in multi-variable Calculus (the class just started today). I'd prefer to have something pleasant to read over Stewart's cookbook, and I'm thinking about purchasing Courant Volume II. Do you guys think I'd be okay to dive into this? I read part of Volume I a while back and I remember his writing being extremely clear, which is why it was my first choice.
