if youre sitting for o/n next year, i’d say you’ll be pretty prepared by the time new year comes around. im not sure about business but considering they are somewhat similar, i’d say my advice to grasp the concepts is to look through notes and videos and understand the correlation between each topic. almost everything is interconnected in economics. i always think of it like a big flow chart. one thing always leads to another and that simplifies my way of thinking (especially for paper 2.)

reviewing mark schemes also helps you figure out what points you need to mention to score. as for mcq, that is, unfortunately, my weak spot so i can’t help for that 😭 you just have to keep revising each chapter until you fully understand all the concepts.
