I'm starting my 2nd year of university this fall, and am trying to improve upon my 1st year mistakes. Biggest one is the amount of notebooks I used. I usually take notes in class (1 class/notebook), as well as read and takes notes from the texts on my own time (another ~1 or 2 classes/ notebook, separate from the class notes), as well as using another notebook still for practice questions from the texts (approx. 1 per class). In total this can add up to actively using 10-12 notebooks each semester. It feels wasteful and inefficient. How do you guys organize your notes? Any suggestions for me to improve?
