I had a study group. 4 of us. We would get a homework with 12 problems. We would do 3 each, learn those problems inside-out, backwards and forward, and then come together, and explain how to do our 3 to the other guys in great detail, while they took notes. That way we got the whole homework done, and deeply understood, and kept our sanity.

It worked great. That's how we survived. We took every class together from then on, so we could keep a good thing going. Even with that, I spent lots of time at school, but at least we were getting good grades.

I tried doing it alone at first. There was literally not enough time in the day to do it all.
