I took calculus 2 before the summer and I got a b+/a in the course. Now, at the end of the summer I have to take calc 3. IS calc 3 much harder than calc 2? I was told that Calculus 2 was the hardest, but I don't know. My fear is that in my calc 2 class, we were allowed to have "cheat sheets" on our tests. Essentially an index card with anything we wanted on it. So I had some help there, which I doubt in calc 3. But what do you all think? Is calc 3 harder than calc 2?
