i usually am done by 8. i had to stay at work late yesterday and didnt get out of the library til almost 9 and noticed that the LR section i took around 8ish was tougher for me then normal. i did ok, but missed a couple i would have normally gotten and just struggled with more questions then i normally would have.
so yeah, especially at this late stage in the game i would probably try to do most stuff during the day. i am saving my 3 new games sections for M-W-F of next week.
