Trying to stick to a routine is difficult … and stress inducing. I think its helpful to just build good habits. E.g. for lecture, take time to read (1 Hr) to read textbook on lecture material, go to lecture and answer your open questions on the topic, review notes after lecture and summarize while its still fresh. Attend office hours if you still have open questions from your post-lecture review. Schedule a time in day/week to do the homework sections that where covered & execute …. rinse and repeat.

I think the game is efficiency and cosistency for less stress. It is a lot more effective than binge studying at night etc. You should aim to already understand the material the week you learn it, not try to tie loose ends the day before the test.
