look at the dates, HD & TDM - the OP has less than 5 days to work through a long document, the screwing up of which will spoil his/her chances, & waste valuable time - flippant "try harder" comments really don't help.
Well put Phil - & for the OP, you're already in a learning frame of mind at college, so that should help but, your college exams are for the long term; putting those at risk for ATC wouldn't be worth it. The expectation is that you will be able to answer questions based on the booklet, so if you feel you won't be able to do that, you're not prepared enough, yet. You're the placed best person to judge whether you can make it work for you, but there'll always be another stage 1 day - perhaps better to delay for a date that fits if you can; if not, make that time count as best you can. Interviews are about feeling as comfortable as you can, being prepared is a big part of that. Good luck, whichever you decide.
