Yeah, I'm doing all that. For the month leading up to the exam I'll be adding fifth sections from old LSATs. Hopefully that won't throw me off too much.
Any general thoughts from anyone on taking it early? June is a long, long way away.
The 5th sections should be from new LSAT's, not old LSAT's -- at least on the last 4 or so. You want to be sure you're equally challenged on the 5th section, and the newer LSAT's tend to be harder. You should also be sure you calculate your score using the 5th section as well. (Drop your best "real" section, and use the experimental instead to calculate two scores for every exam.) That way, you'll be motivated to do as well as possible on the 5th section, just like on the real thing.
Like I said in my last post. DEFINATELY consider the possibility of taking it early. I believe that you could easily be prepared as early as October.
As far as 5th section goes, I did NOT like the idea of pulling a 5th section out of another preptest because there are only a finite number of PTs available and I didn't want to 'waste' them by using them as experimental sections. Instead, I chose to build my endurance by taking 2 tests a day. Generally with a short 30 min break between exams. If you can stay sharp for 8 sections, you should be able to stay sharp for 5 on the real test day.
