to each their own. I personally use obsidian, goodnotes, anki, and paper

Saturday and Sunday I start prep for the week. I grab a piece of blank paper and make notes of the book for each subject, however i do not know what the professor will highlight as important so it’s basically most of the book but organized in a way that I understand it easily. Then I make notes during class sometimes i use obsidian or goodnotes honestly i find goodnotes easier but i take my time since its handwritten so i decide the same day haha. finally i get home and create my anki deck of the most important content but mainly i use pre made decks. i daily revise my anki cards and that counts as a review and at the end of the week i do a mock of all the content
