Official Practice Test 7's math section, every question, solved in one continuous run with the fastest method for each. On this test that is very often Desmos: type it in, read the answer off the graph, move on.

This Deep In, Audit Your Speed Too

By your fourth or fifth full test, the question types should be starting to look familiar. So Test 7 review is not only about which questions you missed. It is about which questions you got right slowly.

Here is the audit: for each question, compare how long your route took against the route in the video. Anywhere the video finishes in twenty seconds and you spent two minutes, you have found banked time, and banked time is what lets you give the last five questions of Module 2 the attention they need. Usually the gap is a Desmos move you were not using, which is exactly the advantage we broke down here.

New to reviewing tests this way? The full method is in the Test 4 post.

Common Questions

In the video above: all 44 math questions from Bluebook Practice Test 7, solved in real time in order. Bluebook gives you an answer key and short rationales; the video shows the fastest route through each problem, which is often 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 80 minutes like a movie.

Not as a measurement, because memory inflates the score. Sigma Prep Test 7 mirrors the official test question for question with fresh problems, in three versions, so you can check whether the skills are really there.
