FIVE QUESTIONS. NO STOPWATCH.
A little practice goes a long way.

Write your reasoning on paper before checking. An exact fraction and its equivalent finite decimal are both accepted. The score counts correct first attempts; revealing an answer does not earn a point. A wrong attempt is a useful clue about which step to revisit.
These questions are for self-study. No answers, scores, names, or class details are uploaded or saved after you leave the page. Review a guide whenever you need a refresher.
