MCQ Generator

Builds multiple-choice questions from your own notes, with wrong answers taken from the same document and matched to the length of the correct one, so no option can be ruled out at a glance.

Generated from your material

Wrong answers that are actually plausible

The distractors come from your own material and are matched for length, so they look like they could be right. Generators that pull wrong answers from a generic list produce questions you can answer without knowing anything, which tests nothing.
Why use it

Built to be genuinely useful

Distractors from your material

Every wrong option is a real term out of the text you pasted, not a filler word from a generic list.

Matched for length

Options stay within three characters of the answer, so the longest word is never automatically the right one.

Answer position shuffled

The four options are reordered for each question, so the answer does not settle into one slot.

Nothing leaves your device

The notes are read and turned into questions in your browser; no file or text is uploaded.

How it works

Three steps

  1. 1

    Paste the notes or chapter you are revising.

  2. 2

    Generate the set and answer it cold, without scrolling back.

  3. 3

    Check each answer against the source sentence shown beside it.

Why generated MCQs are usually too easy

A question is only as good as its wrong answers. Most generators pull distractors from a fixed word list, or from anywhere in the document, so a question about photosynthesis ends up sitting beside 'the', 'and' and 'which'. You can answer that without reading the stem, and the mark it gives you means nothing. It measures whether you can spot an odd word out.

Length is the tell that gives a bad question away fastest. Students learn, often without noticing, that the longest and most technical-looking option is usually the right one. Here every distractor sits within three characters of the answer, so a twelve-letter term is offered against words of nine to fifteen letters taken from the same chapter.

Position is the second tell. Question banks written by hand drift towards putting the answer in the second or third slot, and anyone who has sat enough papers knows it. The four options are shuffled independently for each question, so there is no position worth guessing and no pattern to learn across a set.

How each question is built

Each question begins as a sentence from your notes with one word removed. The word chosen is the rarest in that sentence, measured across the whole document, because that is nearly always the term the sentence exists to teach. Blanking a common word like 'process' or 'because' would produce a question about grammar instead.

The three wrong options are then taken from the vocabulary of the same document, filtered to words within three characters of the answer's length, and drawn at random from up to forty candidates. A sentence that cannot supply three such words is dropped rather than padded out with options that would give the answer away.

The stems are your own sentences, unchanged apart from the blank, and every option is a word that already appears in your notes. Nothing is written for you. The trade-off is that a distractor is judged by its shape rather than by whether it is conceptually tempting, so expect to discard the occasional question that reads oddly.

Getting a usable set out of a chapter

Objective sections in Indian university internals and competitive papers are built much the same way: a line from the prescribed text with one term at stake. Reading a chapter once, then attempting questions built from it a day later, tests recall rather than recognition — and recognition is what collapses in the exam hall.

Six hundred to eight hundred words of dense material is roughly the point where there is enough vocabulary to work with. A single paragraph will yield two or three usable questions at best, because there are too few terms of similar length to draw on. Paste the full section rather than a summary of it.

Because the distractor choice and the shuffle are both random, running the same notes again produces a different set. That is worth doing for a second pass a week later: the sentences will be familiar, but the options beside them will not, so you cannot coast on remembering where the answer sat.
