hey everyone! im studying almost completely online meaning my uni is remote based and i mostly acquire all my knowledge from reading the materials.

thus, i am asking if anyone knows any valuable tools to help especially with notes and knowledge retention. i mean, it’s so much information and i have no professor or such filtering the most important things for me. currently, i have no smart tools so anything that you have to recommend will be useful (preferably free).

thanks in advance!
