Ha, you just said- not be silly. You? Ha. If only Sarah Palin really would run for president.
OP- think of it this way: you can be like one of the rich people that can afford to study for the LSAT full time for 6 months to a year. I've met them. If you look, you can find them on LSD. They lucky and they score well. A year and a half isn't really enough time for anything to significantly change, regardless. Now if you said last you took the LSAT was 1990, well that's a different story, but a year or two, nah.
