I first took the LSAT last October. I didn't take a prep course ; I just studied the Powerscore Bibles and took old LSATs. I was scoring 158-161 before the exam and ended up getting a 158.
I decided to retake in December because I was originally shooting for a 160. I signed up for Testmasters course online ( the real one ) and was scoring between 164-167 before the exam. However, my nerves were really terrible and I ended up with a 156.

I really regret not canceling my score.
I took a PT yesterday and after 2 months of not studying I got a 160. I'm also planning taking Testmasters Live Course for the June exam since I'd recieve the re-takers discount.
I'm in the LA area and my top 3 schools are USC, Pepperdine, and Loyola.
I know my scores are no where close enough , and even my higher scores probably won't cut it for USC. However, I'm just worried my nerves will cause me to screw up again in June. :/
