I think that website with all the notes about the synoptic essay also has loads of notes on units 1-5..
I'm not going to revise page by page, it would actually be impossible to memorise all of the information in the book! It's not needed anyway, the essay is literally a 'synopsis' of what you know, a brief summary, of all the main points. I don't know how I'm going to revise for it though.. might just do some condensed notes on past essay titles. Hows general unit 5 revision going? I'm on chapter 16, definitely the worst one of the lot!
