you're a CS major if I remeber right... meaning you've failed at every other decent major out there.
But ya, Diff EQs isn't too bad, multi D calc can be a bit tough though with them triple integrals and switching between spherical, polar, and rectangular coordinate systems. However, I have found linear algebra to be ridiculously easy, as were calc 1 and 2.
That's all I've taken thus far 3 semesters in college (the current math course I'm in is a 2 semester 12 credit exploration based mixture of multi d, diff eqs, and linear algebra). I will be 1 class away from a math minor after taking a engineering stats course, so I am thinking I'll take another more advance linear algebra course and call it a day.
But ya, if you need homework, feel free to ask, there are enough of us math nerds here to help you.
