I’ve tutored calculus. It is very hard to teach math in an understandable way.
Props to this guy.
He had 3 papers published while at PSU, taught Trig and Analytic Geometry, and earned a Masters degree in Math Education. He’s halfway through his second Masters degree, and wants to get his PHD from MIT.
When others bailed during the sanctions, he turned down an offer (and real future scholarship money) from Stanford to stay with his teammates.
Like I said - great guy!
