The full math section of official Practice Test 11, solved in one take: every shortcut, every Desmos trick, nothing edited out.

Jump to: Module 1 (0:28) · Module 2 (21:32) · 48 minutes in all, 22 questions per module.

What to Do After the Last Official Test

If you are reviewing Test 11, odds are you have been through most of the others, which means you are about to hit the wall every serious student hits: College Board's tests run out, and retaking one you remember tells you almost nothing. We wrote a whole piece on what to do when you finish every Bluebook test, because it is one of the most common questions we get.

The short version: keep learning from your Test 11 misses the normal way, jump to them in the video, tag them as unknown type or giveaway, drill the types. The review method is in the Test 4 post if you want it spelled out.

All 44 Practice Test 11 Math Questions, One at a Time

Every math question from official Practice Test 11, in order, as it appears in the walkthrough. Each one has the correct answer, how it's solved, and a clip of just that question.

Common Questions

After you submit Practice Test 11 in Bluebook, your full results are in My Practice on the College Board site: every question, your answer, the correct answer and a written explanation. College Board also posts a printable version of Practice Test 11 with an answer key, answer explanations and a scoring guide. The video on this page adds the fastest way to solve each one.

On this page. Every one of the 44 math questions from Bluebook Practice Test 11 has its own section, from Module 1 Question 1 to Module 2 Question 22, with the correct answer, the skill it tests, how it is solved, and a video clip of just that question. The full walkthrough video above solves all 44 in order, often with Desmos rather than algebra.

Take the test timed in Bluebook first, score it, and pull out every question you missed or guessed on. Then jump to only those questions in the video and ask one thing for each: could I have recognized this setup, and did I know the move? Do not watch all 48 minutes like a movie.

Not as a measurement, because memory inflates the score. Sigma Prep Test 11 mirrors the official test question for question with fresh problems, in three versions, so you can check whether the skills are really there.
