As the title says, do you learn math faster by working on problems in groups, where you can discuss your solutions or by doing it all by yourself? I can't see any advantage of working in groups because if you get stuck on a problem, you can just ask the smartest person in group how he or she solved the problem which means you won't have to work as hard.
I want to know what professional mathematicians think. Are people (like me) who prefers to work by themselves missing out?
