Self-Study Practice Set · No. 04
Twenty questions, sequenced from identifying rational numbers to rationalizing conjugate-pair denominators. Work through them once, honestly — the goal is a single clean pass.
Pick a time limit and begin. Each answer gives instant feedback with a short explanation. When time runs out, the test locks and your score appears automatically.
Only the questions you answered incorrectly are shown below — skipped questions aren't included here.
