I found calculus easy. But Linear Algebra was my downfall.

I found Lin Algebra easy too.

The hardest one for me was Partial Diff EQ's. But once I figured it out, it became easier. Still not an easy course to get done.

“Difficult equations” was the hardest math class for me. The hardest class overall was Signals and Systems. Analog and discrete math applied to analysis of communication systems. Ugh.
