Bluebook holds College Board's own free full-length practice tests. Here is what College Board's pages actually say: the timing, the embedded Desmos, the app-only access, and the one thing they never print (the test count), plus a plan that treats the stock as finite.
One difficult question does not tell you your score.
How do I get the most out of the official practice tests in Bluebook?
Download the Bluebook app, open Practice and Prepare, and take the free full-length practice tests there. Take each one under real conditions: 64 minutes for Reading and Writing, 70 minutes for Math, with the 10-minute break between sections. Review every missed question before you take the next one. One more thing to know: as of this writing, no College Board page states how many full-length tests are in the app, so treat the stock as limited and space them out.
The facts below come straight from College Board pages, checked today.
1. Baseline first, then drill. Take your first test under exact real timing with the break, before any heavy studying. You need an honest diagnostic. Then spend one to two weeks drilling your weakest skills between tests, not the day before the next one.
2. Practice the tools you will use on test day. Do every practice test inside Bluebook rather than on paper, so the Desmos calculator, the timer behavior, and the module structure are familiar before they matter. If you plan to bring your own calculator, still learn the embedded Desmos, because it is your backup if yours fails.
3. Review is where the points are. After each test, open every missed question and classify it: content gap, misread, or time crunch. Re-solve each miss without looking at the answer until you can explain why the right answer is right and why your choice was wrong. A test you do not review is just a score, not practice.
4. Space them out. Because the official stock is limited and College Board does not say how many there are, do not burn through several tests in a week early in your prep. One full test every two to three weeks is enough for most students, and save the last one or two for the final two weeks before your test date.
Do not take practice tests with your phone next to you, do not skip the break, and do not let a good score on one test convince you to stop drilling. One clean run under real conditions is worth more than three casual ones.
