I'm currently taking a course in Theoretical Mechanics, which is a prerequisite to General Relativity, which I'm very much looking forward to taking. However, I'm not that good in mechanics, and Real Analysis seems to be more straightforward than even the first course in Mechanics. I'm quite comfortable in Applied Math, and, to a certain degree in Pure Math (especially Abstract Algebra). I've also taken Quantum Mechaics, and got a very good mark in it, one of the highest marks ever (compared to other courses). My question is: how heavy is General Relativity on the side of Mechanics? I sincerely hope that it has "too much" "hardcore math" than it has any "hardcore mechanics".
