Since the summer, I have been prepping for December.  My practice tests were mostly 155+ and a high of 159.  I scored a 153 in December and was disappointed.  I was hoping to somehow score a 160, but now that this is over with I have realized attending a third tier school would be a mistake.  I was going to settle for one and apply in the fall, but screw it I just don't want to do it.  I have a 3.91 GPA in business and management, and I realize I could have a much more difficult major.  This GPA is still good, and if I can just go on from this 153 glut and get in the 160s I would be happy.  Timing is still an issue with me and I didn't get through 1 whole passage on RC, 1 whole LG, and about 5+ questions on each LR.  Perhaps more practice would bring me to a 160 alone with just timing.  I was using blueprint to prep, but I still haven't gotten the methods to stick well.  Is there someway i can compile explanations to all LSATs or get something that has them?  I already have all the practice tests.  
Another concern I have is that I won't do much better than I currently am.  I have taken about 10 timed tests and did months of drilling, but this leads me to believe this is nothing after more carefully evaluating what you guys have done.  I did start at a 143 diagnostic which is lower than almost anyone here.  

  The SAT and ACT didn't bode me well as well, but based on the formula for SAT/ACT to LSAT conversion I should be at least getting a 158.  I am afraid that if I keep prepping, I will reach a plateau at 158.
I'm not a T14 or bust type of guy (hell, I shouldn't be based on my scores), but I do dream of going to a school like UCONN, BC, BC, ND, GW, Vandy, and perhaps one of the lower T-14s if I can do well enough on the LSAT.  I hope I can do it.  The SATs and the ACTs make me believe that my ceiling for the LSAT might soon be reached which worries me.  Most of you probably knocked the SAT out of the work.
Let me know what you guys think.
