I (20F) am on my second year of college. It just really pisses me off when people want to take advantage of me. I work my ass off to study and prepare study notes. The issue I have is that my friend group is always making fun of me because I am the "study nerd" but when exam season comes around they ask for all of my notes. They are really pushy and I don't know how to tell them that I don't want to share the notes that I spent HOURS writing. Any tips¿
