Can I retake/redo practice tests for pacing practice?

Yes, and retakes are useful for practicing pacing and test-taking habits. Just know that you'll likely recognize some questions, which inflates your score and makes it unreliable as a performance measure. Use retakes for execution practice, not as score benchmarks.

One of the most valuable things a practice exam gives you is a record of your time per problem. On a first attempt or a retake, review where you spent too long, where you were efficient, and where your timing decisions cost you points. A retake lets you work on those patterns without the added stress of unfamiliar content.
