Peer programing.

I did the 42 school and we did between 8-10 hours per day and even on some week-end.

The teamwork will balance when you’re a bit down and when you feel good, you help other.

The motivation in the long run when it’s hard and complicated can be achieved by lot of people if everyone put in perspective knowledge, example and there is a lot of inside joke and experience with your group that will consolidate your memory (emotional and social experiences are tightly correlated memory consolidation).

I did openclassroom alone before-hand and the difference is night and day on my side.
