I’m not sure about an addendum, but a higher December score may help depending on when applications are due and if the schools you’re applying look at all LSAT scores or your most recent score, or your highest score. Sometimes different schools have different policies on which LSAT score they will use for admissions and if you score closer to 160 (which may be saying to do a lot over the next month), then they may just need your most recent or highest score which obviously benefits you. Sometimes they average out the scores as well.</p>
<p>I get the feeling a high percentage of students who score in the lower brackets of their schools’ target LSAT scores try to explain ‘why’ through the application via essay or extra tid-bit. It’s common belief that LS admissions is a numbers game, so I wouldn’t bet on there being much of an effect with extras.</p>
<p>Best of luck.</p>
