actually, i thought calc 3 was alot easier to understand than calc 2. calc 2 is all integrals, and calc 3 is basically partial derivatives and surface integrals. the integrals are a whole lot easier since you don't have to remember all those trig identities for integrals. although i have heard of at least one person dropping out of GT altogether just because of failing calc 3. it gets even worse with differential equations.
and differential equations is the last math u need to take for ME right?
