Then you can swear at people and they won't get you!
You should read it. Like, now. It is one of the most brilliant books I have read, but it is
not a good idea to study the Holocaust and then start reading a book set in Germany during WWII, with lots of Nazis and Germans. Especially not if the book makes you cry, because then you end up crying over your textbook
I dunno about GCSEs, but our 'paper' system is different. Every extended (further) paper can cover any topic from the whole syllabus, and core papers can have questions from anywhere in the core (standard?) syllabus. the 'papers' indicate the course route you take and the way you answer. So, for example in Sciences, P1 is multiple choice (core), P3 is brief answers (extended), P5 is practical (extended), P6 is alternative to practical (extended), etc. I was under the impression that modules are organised by subject matter—like I'd sit a module exam for co-ordination and response, or for reproduction. Is that correct?
If linear is what I think it is, then it only improves your recall
There's nothing wrong in making you revise it 'till it sticks, is there?
