I agree with Itera and Bchad on these.  Make your last few study sessions as similar to the exam as you can.
If you’re going to use earplugs, start getting used to them now.  (At least if earplugs become a distraction, you can always pull them out.)
If you’re going to chug Red Bull mid-day, start doing it now.  (If you chug Red Bull at 1:30 and it messes with your system, it’s hard to “un-chug” it.)
Stop studying to music.  Can’t have it on the exam, so get used to it now.
You know you’re going to have to think for three hours straight–get some practice now, or you’ll find that your brain gets tired.  (You can build your mental stamina, just like you can build your physical stamina.)
