AS level business Paper 1 and 2 Revision

I need help on how to study business, so far i do tiopical past paper questions ,to me that sounds like the best way to study but i want to know if anyone seeing this has a better way or i am on the right track as i am writing in a months time

if you are doing edexcel i would say first make flashcards that are active recall of each questions and make it into a topic. also have digital or/and physical flashcards that contain information for the key terms and definitions as it helps to gain KN marks
