Why have you asked this in the Paper F2 forum? Consolidations are not in the syllabus for Paper F2 – it is Paper F3!!
You must watch my free Paper F3 lectures on consolidations where everything is explained. I am sorry, but you cannot expect me to type out all of my lectures here 🙂
Our free lectures are a complete course for Paper F3 and cover everything needed to be able to pass the exam well.
