But I know that during the time that we were in class suffering through boring lectures that often made no sense, he was dissecting each and every handout, combing through mutliple textbooks he got from the library and downloading and reading every journal reference in the class notes.
The crazy thing is, I think he learned more than any of us who had perfect attendance at lectures.
I know he wasn't the "smartest" guy in our classes but he often knew more about certain areas than even the MS and PhD candidates who were assisting us in labs. He was just getting much more out of the things we did because he had some background going in.
The guy was just super curious and did his homework like nobody's business. Sheer effort. It was impressive.
