You already know that taking real LSATs is vital to improving your score. But properly reviewing the tests you take will really take your score to the next level.
First, let's look at how most people review. They take a timed test or section. When they finish, they flip to the answer key and rush to correct their work. "Yes, I'm right - I'm awesome!", or "Argh, I'm wrong - I suck!".
You probably review this way - I did when I started out. Heck, there were times when I flipped to the answers mid test. I just couldn't wait to check.
Unfortunately, this is an AWFUL way to review. Think about it - you don't really care if you were right. This isn't test day, so your points don't count. Some answers might just have been lucky guesses.
You really care whether your reasoning was right. And it's hard to check your reasoning if you check the answers first. Once you see that the answer is D, you'll invent reasons why D is obviously correct. I see students make up wrong reasons for right answers all the time.
The trick is to review questions before you check your answers. We call this Blind Review, and it's the best way to study. For details on how to do it, check out this video we made explaining how do Blind Review.
