I had planned so i would finish q bank exactly one week from my exam. Then for the last week i was just trying to simulate the exam conditions, namely wake up at 8am, shower-coffee-breakfast until 9, and then i would do questions using the random mode at 1 hour bursts, with small breaks in between until 5pm. At that point i wasn t doing timed tests, I just wanted to keep contact with the test's format, and if I happened to learn something new, even better. I wasn't forcing myself to learn anything new at that point, cause everything new that would go in at that point would probably be a detail, and it would likely take the place of something more important. After 5pm I would go to the gym, or rot in front of the tv,or even do some more questions, depending on how i felt.
And for god's sake, don't dare studying anything the last day. You can only harm your self by doing this. Just relax, spend some time with a friend or gf, watch a movie, in other words chill out.
Hope it was helpful,
Theodore
