Hi , i suggest you to start from the beginning 🙂 simply open the syllabus that is available at accaglobal website , get your books and follow it.
I believe it’s a good idea to start from IASB framework, because it’s a bit boring and needs regular revision. so it’s good to start with it early. Later on it’s up to you, you can move on with consolidations ..well just like syllabus proposes it. Consolidation will take quite a lot of time, so it’s also good to start with it early.
