M2, judging from your score, you stink at games. just like i do
but take heart. i was missing between 9-12 questions per games section initially, but have improved considerably.
your plan sounds like a good one. but i would also reccomend getting the logic games bible. work thru it prior to beginning your practice on actual LSATs. i was astounded at how helpful the approaches for tackling games were in this book, but when i began practice on timed sections, i found under the pressure, i would get away from the methods i had learned.
but after i crossed the 10 games section threshhold, something happened. i began getting better then 3/4 of the questions right in timed sections, and even much better. all i can say is that i gradually saw similarities in the games that helped me to get thru them quicker. i also became more aware of my tendency to transpose rules.
anyway, best of luck, and let us know how you do. i broke 170 on my last 2 full LSATs, and with about 25 full tests left to take, i am feeling pretty good.
