i am probably not the best example, as i never finished my degree, but studiying is the one thing where pomodoro timers were actual helpful for me, but nothing was better than having a small group of people to study with.
Working on problems together on a whiteboard was almost magical, because so much stayed in my brain without totaly draining my batteries.
other than that keeping things fresh and fun is important, to this day i'll draw pictures on my notes when going through them, emphasize stuff by putting it in speech bubbles or write stupid stuff in foot notes.
i also sometimes experiment with different note taking techniques, but it's mostly bullet points.
