Good luck!!
Let me know how it goes 
Make sure the supervisors actually remember to give you paper to write on... not like in my prac exam...haha.
Ha! I had to tell them right at the end of writing time that they didn't give us paper.
I went alright with the time limit, I glanced over one of my passages for In Cold Blood at the start of reading time, then dedicated the rest of RT to Hamlet passages. From then on I spent about 50 or so minutes on Hamlet, gave about 10 mins for planning reading of In Cold Blood and the rest of that time I dedicated to In Cold Blood. I left about 5 minutes to myself just checking over both passages. That's my plan leading into the exam too, might make some slight adjustments, though.
I haven't had much time to prepare for it over the holidays, but the few passage analysis essays that I have completed I've made sure not to go write for over 70 minutes for each one.
