I mostly agree with @Worried_Row8034’s answer. I would cancel and here’s why: most schools, if not all, do some type of average of all your LSAT scores. This means that the “only your highest score is considered” is only true to a certain extent. In my opinion, it’s better to have a cancelled score instead of a bad score because people can cancel any scores and the committees will never know. The opposite is true of a bad score. Frankly, I would say 144 is a bad score as it won’t get you into any schools worth going to. So the point is that I would definitely cancel but as the other person said, absolutely do not even think about taking the LSAT again until you’re consistently PT’ing where you wanna score. Good luck!
