Well, I don't know you, your teacher, or even what subject we're discussing but you wrote that you did "not have to bother with homework and assignments". Perhaps you would have learned more if the instruction had not failed to make you study? :P

Whether they'd be able to make me study (it was a mathematical analysis course, though I do not think it matters) is a question that'd be hard to answer — I was already highly motivated with different topics: I was spending my time reading on CS topics like algorithm complexity, operating system development and building software interfacing with hardware. So another possible outcome would have been that I simply learned less of it due to lousy instruction — which was the case with a few other subjects.

Sometimes a teacher can also do a great job of getting you interested (also important) but I was focusing on quality instruction.

Or maybe OP is just naturally gifted at math.
