it depends. i think i'm going to slow myself down on purpose to make sure i don't make any stupid mistakes. most mistakes i make are because i'm rushing. i've been using the FE manual that they give you while doing the review so that i can get used to where things are in the manual.
thats good. you'll have plenty of time. don't rush. and do go back and check it over. even doing that, i still had over an hour to kill between sessions.
