My newest class starts tonight; multivariable calculus. I managed to claw my way through the first two calc courses, but I'm not so sure about this new one. First off, it's at harvard which is going to be harder to begin with. Secondly, the professor made a point of mentioning in the syllabus that this course would likely be harder than other courses, and it's virtually impossible to pass without a significant amount of time and effort put into keeping up to speed. Gulp. I'll let you know how it goes.
