Practice Tests
I recommend only using official College Board practice tests when prepping for the SAT. Here are four linear tests. Although these are not the adaptive, online tests student will be taking, the questions are exactly the same as what they will see on test day. These linear tests are a good place to start prep before using the four Blue Book tests that are online and adaptive.

Registering and Blue Book tests at The College Board
You will need to register for the test here. Once you’ve done so you will have access to the four Blue Book tests. These are great resources for practicing because they are exactly the same as what students will see on test day. I recommend using the Blue Book tests after students have mastered the basics using the linear tests linked above.
