In high school, I was doing poorly in my freshman math classes partly because I had terrible handwriting and my '6' looked like a 'b'. Try keeping track of your work when you're using the quadratic formula :P

A friendly biology teacher recognized my plight and helped me retrain my handwriting into something legible. It still isn't great, but at least I don't make that mistake anymore.

I had to do the same thing in college with t's and +'s, I resisted curling my t's in physics and math class for a while until it was explained to me that everyone did it.

Yeah I started crossing my z's in Calc II because I was getting them mixed up with my 2's.
