The wrong answers are the part that took the work

A distractor nobody would pick makes a test look hard and mark easy. These are written to be the mistakes people actually make — and when you pick one, it tells you why it was tempting, which is the misconception worth fixing.
Why use it

Common confusions and near-miss values, not obviously silly options that inflate your score and teach nothing.

Scored as you go

Click an option and it is marked immediately, with a running total and a retake button.

Why each wrong answer is wrong

The misconception behind the option you picked, which is the thing worth fixing.

How it works

Three steps

  1. 1

    Paste your notes or upload the lecture PDF.

  2. 2

    Pick how many questions and how hard.

  3. 3

    Answer each one — it marks instantly and explains the options.

The wrong answers are where the work goes

Writing a multiple-choice question is easy. Writing three wrong answers a student who half-understands the topic would genuinely consider is the hard part, and it is what separates a test that measures something from a test that flatters you.

An obviously wrong option is not a distractor; it is padding. Three of them turn a four-option question into a one-option question — you score highly and learn nothing about what you do not know. That is the failure mode of almost every automatically generated MCQ set.

So the generator is pushed towards the mistakes people actually make: the commonly confused term, the value that is right for a neighbouring case, the definition that is nearly correct. When you pick one, the explanation names the confusion — and that confusion is the thing you came to find.

Why the correct option is not the longest one

There is a well-known tell in badly written multiple choice: the correct answer is the most detailed, because the writer knew it best and elaborated. Students learn to spot it within a term, and from then on the test measures test-taking rather than knowledge.

The same goes for grammatical agreement with the stem, for absolute words like always and never appearing only in wrong options, and for the correct answer sitting in the same position too often. Each lets someone score without knowing anything.

The generator is instructed against those patterns. It is not infallible — if one option looks obviously different from the rest, that question is weak and worth regenerating.
