I took the kaplan lsat extreme course to prepare last time. To date, my highest practice score was a 168. Usually, I score anywhere from 163-166 on practice tests. It is getting harder to practice this time around because I have already done most of the released lsats and so my score might be improving because I have already seen the questions in the past. You are saying that I could get into a less picky T1 like Boalt with my current numbers? How about a school like Georgetown? Would I have to retake to get into a school like Georgetown? If so, how much do you think I would have to go up in my lsat score to have a shot (more than 2 points)?
To be honest, I don't think you should re-take. You scored at the high end of your practice range, you've used up most of your prep materials, and I'm not really getting a sense from your posts that you have a strong desire to re-take or think that you could do better. Part of doing a re-take is if you think you could score more than 3 points higher. Yes, most schools take the higher score these days, but re-taking and getting a 167 or 168 will probably still place you in the same score band. it seems to me, is a waste of your time, energy and money. If you have a burning desire to do a re-take and are willing to do extra work for it, than by all means go ahead. But I don't really get that sense from you from your posts.
