I can't stress this piece of advice more urgently:
Order PrepTests 43-46 from LSAC. Those are:
They're all practically identical in number and distribution of questions, and they show, I believe, the increasing level of LR and RC difficulty (though more RC than LR), and the increasing easiness of games.
You can't order the February 2005 test, but that's the one I took, and it was a near carbon-copy of the other ones.
If October 2005 follows the trend, you'll see:
3 pretty straightforward RC passages, followed by an unforgiving one (Bach in FEB, legal theory in JUNE);
3 pretty straightforward games, followed by a very difficult one (for me, anyway; those who are great at games had no trouble with any of the games from the past few tests.)
LR sections that lull you with relatively easy questions early, then throw a bunch of dense, wordy ones in near the end, sprinkled with thorny parallel and formal logic questions.
More than anything else: Beware of the RC. It took a chunk out of my butt in February, and it hurt alot of high scorers in June, too.
