Don't try to plan to do too much. I ended up reviewing all of the rapid review section and pictures at the end of first aid. Between that and looking up a few tables in Goljan that I thought were important, that took me to about 6 pm. At that point, I called it quits for the night and went to the gym.
One of the most important things you can do (especially if your test is early the next day) is get everything ready for the day. Make sure you have your permit printed out (with an extra copy in your car or somewhere else), and pack your bag for the day (including your ID!!). It will make things much easier on the day of.
