how to get better at civ102 (fillerrrrrrrrrrrrrr)

Hello, I am a first year engsci currently struggling with civ102 :( I barely make the pass mark in the weekly quizzes and sometimes even fail them idk what to do. The concepts are pretty tough for me to understand sometimes so it means I have to allot a lot more time to this course, and previous lessons and it makes it hard to catch up to the current content (which I also don’t really understand). Does anyone who has taken this before have any tips on how they’d go about studying/doing practice problems I’m really scared I’ll fail the final
