Another revision night...

One more sleep, then I have an exam with 250 questions and 6 hours to complete it. I need to get 70% or more to pass.

I've read three different study guides, listened to a number of podcasts, reviewed questions in books, questions from applications and questions online. I've reviewed and re-reviewed what I do, distilling my need to know to a smaller list, then some strange results happened...

From one set of online tests I'm averaging over 85%, a test from one of the books I'm getting 70% and a set of questions from another book I got 45%!

I have to be up in 7 hours (5:30am) to get to London in time, so I'm not sure what more I can do except sleep!
