Let the time limits press you. In running, the best way to improve a 5k time is to practice performing at the desired pace over a short distances, and then stitch those short distances into a longer distance while keeping up the desired pace. The LSAT is like a 5k. Practice going at the necessary speed, even if you fail at first, and you will be able to stitch the pieces it all together in time.

If I get a 170, then I wished it into being...

I wished 170 into being, so I will get a 170! Right...?

I have a real problem with this one. The text states AA→UA→CS and the conclusion states AA→CS (all those (only) who appreciate advances are computer scientists). It does not say that all CS→AA. I don't see how such an assumption can be drawn since the conclusion explicitly says AA→CS.

Tricky!
