    1. Be as excited as you can be. Rigorous argument is not necessarily the most enthralling of things, but people pick up on whether you care about something and that can make a big difference in their opinion of the topic.

This is so important. My precalc instructor was boring AF and I remember none of it. My DiffEQ instructor got so carried away that the prof next door would come over and tell him to stop banging on the chalkboard. As a result, I think DiffEQ is the fundamental magic that makes the world go 'round.

Well, that's also because engineering is like 50% differential equations. My diff course was pure math and zero applications and it was the. absolute. worst.

It's funny because mine was math so pure that the final was

"Imagine a function that does xxxxxxxxxxx. What would happen if

A) yyyy?

B) zzzz?

C) ppp ddd qqq?"

No numbers. Fuckin' essay-style with roll-your-own functions and derivation. It was eye-poppingly hardcore.

The rate of attrition in that class was such that 15% of the people who started it finished it. I got a 25% on the one assignment he gave all quarter and immediately asked him what I could do to resurrect my grade. he said "relax! You were in the top 20%!"

When all of us were heads down and desperate on that final he said "if you take it home and study I will give you an A."

Fuckin' A I'll bet I could teach Diff EQ even now and it's been 20 years. That class was goddamn amazing.

Maybe it was my professor - he was basically like "here's a Laplace and this is how you calculate a Wronskian so go do that now okthxbai". He never explained why things were done that way properly, so I had to resort to fucking Khan Academy more than once to understand what was happening.
