Every math question on official Practice Test 5, solved start to finish in real time. No cuts, no script, and wherever a problem can be killed in Desmos instead of on paper, that is the route you will see.

Test 5 Is Your First Real Comparison

For most students Test 5 is the second full test they take, and that makes it the first one that measures change instead of just position. One test tells you where you are. Two tell you whether your prep is working.

So before you watch anything, put your Test 4 and Test 5 misses side by side. The questions you missed on both sittings are not bad luck, they are types you do not recognize yet, and those are the ones to jump to in the video. If you have not done Test 4 yet, start with the Test 4 walkthrough, where we also lay out the full method for reviewing a practice test properly.

Then drill what the comparison exposed. The engine is the same one behind the full 800 plan: miss, understand why, repeat the type until you recognize it on sight.

After Test 5

When you want a third measurement on the same material without half-remembered answers polluting it, Sigma Prep has a mock version of Test 5 modeled question for question on the real one, in three versions, each question with its own video explanation. The Test 4 mock is free to try first: full-length timed practice tests. Start free today!

Common Questions

In the video above: all 44 math questions from Bluebook Practice Test 5, 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 5 mirrors the official test question for question with fresh problems, in three versions, so you can check whether the skills are really there.
