Ok: what are most likely questions? Topic headings done on course, pick two, then pick something specific in the two they'll definitely ask. Like what's the course? If it's hitler, they'll be like "how did he rise to power?" Or "what factors led to the night of long knives" K so you've picked two things from the course they'll ask (if you've done past papers, look in them, they'll ask basically the same questions) Now bullet point the important things so it looks like you know what happened, memorise those, write some things on your hand to remind you of them when you go in Then answer as best you can, you get loads of marks just for writing an essay properly with good grammar, don't spell hitlers name wrong, if you're not sure of something say "there's a great deal of debate around whatever, but I will focus on the bit I do know" but obvs don't say that Just write some shit, cross your fingers, if you fail say you were ill and ask to resit :)
