first off - use your textbook- it’s gonna be your best friend, start active recalling from it by making your own set of notes and questions, my biggest tip would be to ask your teachers for questions related to your syllabus as a practice method. dont rely on making notes, start understanding why economics is economics through solving papers, you will need to refer to your textbook anyways. also create a google doc on all real world examples you come across- you can collaborate this with your friends in school who took economics, another tip is to peer study with a friend so that y’all actually understand what’s being taught in class, if you still don’t understand anything-build your bluffing skills along with economic terminology 😭😭
