I highly recommend taking the LSAT again, especially if you think you can do better by doing something differently. I know that the LSAT is not a good indicator for everyone, why else would it have the predictor rate of .5 instead of 1? However, the reality is that they use it because they don't have anything else. Show them that you can play their game, then, don't make excuses for the lower score! Form a solid argument for why they should use the higher score. That's what I did, and I received positive results even applying late January.
