It does look an absolute nightmare doesn't it! I received 2 boxes of binders from Oxford. Just try to break it up into manageable chunks and try to walk through it all slowly without trying to rush. If you don't understand something, resist the temptation to skip it and move on - you will just be left with big knowledge gaps at the end and it is always your weak areas they seem to pick on! The exams aren't rocket science though - solid preparation will ensure a good result.
