The Obama campaign revolutionized political fundraising by making a simple switch: allowing the data to decide instead of the people. They ran hundreds of experiments on different minute variations in how they presented their fundraising asks until they came up with the best formula.

You can do the same thing for yourself by using online study tools like the ones Blueprint has developed. While we naturally think our tools are the best, these tips apply to any system of tools you might find or be using.

Analyze, Analyze, Analyze

When you score a test, Blueprint’s analytics give you a breakdown, by question type, of what you missed. This allows you to keep obsessive track of the questions you missed so that you can constantly be assessing your strengths and weaknesses. Don’t go by what you “feel” you’re good or bad at. Let the data tell you what you need to focus on. It’s more obvious why you need to figure out and practice what you’re bad at.

Knowing what you’re good at is equally important. Often, students will underestimate their abilities on certain question types. But this kind of lack of self-knowledge has implications for your test-taking confidence, which has implications for your test-taking speed. You need to know that you are good at ordering games so you can feel confident enough to handle those quickly and tackle the one weird game that’s always thrown in to each set.

A/B Tests

Blueprint’s online tools can quickly pull from thousands of LSAT questions to get just the ones you need to practice on. In addition to doing focused practice, that allows you to test your methods. Not sure whether it’ll be faster and more accurate to re-draw your diagram or just do it in your head for certain games? Quickly load up a set of comparable games, try it both ways, and choose whichever the data tells you went better.

On the Go

Think it’s too distracting to work on LSAT problems during your daily commute? You have no idea what it’ll be like on test day. At my administration of the LSAT, there was a loud beeping of some timer for 10 minutes of Section One, and street construction (jackhammers!) outside the window during the last section. With a mobile app, you can get in some practice on the go, and you can think of the distractions as just another part of your training regimen.
