Couldn't help it.
Variational Calculus and Integral Equations were my favorites.
This is like Math 101.
But yeah, Nixona, you need to keep two things in mind:
1) Don't simply copy the answer or do it blindly. Understand each step and why its done the way it done.
2) Practice. Helps a lot.
Math is by and large very logical and methodical. So, I'd encourage you never to get confused but to look at any problem as a challenge and solve by "first principles".
Overall, math is not difficult. (Boolean Algebra sucks though.)
