Let’s say I was trying to prove that every time you drink Fireball, you puke. If you wanted to prove the opposite, you’d have to find a way to show that there has not been a single instance in which you both consumed Fireball and vomited. Pretty tough, right? But let’s say that instead, you just wanted to show that it’s not true that you puke EVERY time you have Fireball. You’d just have to show me a single incident in which you had Fireball and didn’t vomit.
The February LSAT is in the books. Compared to the other LSATs in the year, the February LSAT has an aura of mystery about it. Since the test is undisclosed, no one outside LSAC ever gets to see it, except on test day. This leads to the rumor that the February LSAT is weird or different.
