Regarding the math talk, coming out of high school, everything seemed difficult. But after goofing around for ten years and then going back to college (umd) at 28, I remember thinking, “Why did I make this so hard?”
Ended up with a secondary ed math degree including calc I, II, III, Linear Alg, and five or six 400 level math courses.
My point is that all of you thinking you can’t handle the math, I think you might be underestimating yourselves. If I can do it, anyone can.
