Build multiple-choice and true/false quizzes with scoring, timer, and review mode stored locally.
Quizzes you build here are graded by the answer key you mark, and they live in the browser's local storage: reopen the page on the same machine and they are still there, but they will not follow you to another browser, another device, or a private window. You write the questions, mark the correct answer for each, then take the quiz against a timer. The score is correct answers divided by total questions, and review mode shows each question with your answer next to the keyed one. The surprise: the tool grades exactly what you told it, so a mis-keyed question is faithfully graded wrong.
A concrete input and expected output from the current implementation.
Input
A two-question true/false quiz. Question 1: 'Water freezes at 100 degrees Celsius', keyed False. Question 2: 'Earth orbits the Sun', keyed True. You answer False to question 1 and False to question 2.
Expected output
Score 1 of 2, or 50%. Review mode flags question 2: your answer False, correct answer True. Question 1 is marked correct.
Each answer is graded against the key you set: one of two answers is correct, so the score is 1 of 2, and only the missed question appears in review with its keyed answer.
You add questions one at a time. Each entry needs a prompt, the answer choices (two fixed options for true/false, more for multiple choice), and a single option marked as correct, which becomes the answer key. The finished question set is saved to local storage, so it survives reloads on the same browser. Nothing is uploaded; the quiz is only as good as the key you set.
When a quiz runs, questions appear one at a time with their choices, a timer tracks the attempt, and answers are collected without showing whether they are right. Submitting ends the run: the score is the share answered correctly, as a fraction and a percentage. Review mode then walks through every question showing your answer beside the keyed one, and the run's result is kept in local storage.
Yes, on the same browser and device: the quiz and past results are saved in local storage. No, not elsewhere: a different browser, another computer, or a private window starts empty, and clearing site data deletes everything. There is no account or sync to recover from.
Not directly. There is no sharing link and no hosted copy, because quizzes never leave this browser. Another person can take it only on the machine where it was built, or you rebuild the same questions in their browser from scratch.
