- What is an MCQ generator?
- An MCQ generator is a tool that creates multiple choice questions for you, complete with a stem, several answer options and the correct one marked. Instead of writing each question and its distractors by hand, you give the tool your source material and it drafts the questions. PDFQuiz reads a PDF, Word file, slide deck or pasted text you upload and produces ready-to-edit MCQs with an answer key.
- How do I generate MCQ questions from a PDF?
- Upload the PDF, choose how many questions you want, and let the AI write them. PDFQuiz reads the full document, including scanned pages handled with OCR, finds the testable facts and ideas, and drafts each multiple choice question with answer options and the correct answer. You then edit the draft and export it to PDF or Word. The whole process takes about a minute.
- Can AI generate MCQs?
- Yes. AI is well suited to drafting multiple choice questions because it can read your material, identify key points and write plausible distractors quickly. PDFQuiz uses AI to turn your document into a full set of MCQs with options and an answer key in seconds. You review and customize the draft, which keeps the speed of AI while making sure each question says exactly what you mean.
- What makes a good multiple choice question?
- A good multiple choice question has a clear stem, one unambiguous correct answer and distractors that are wrong but believable. The distractors are the hard part, because options that are obviously off let students guess. PDFQuiz drafts distractors from the same source material so they stay on topic, and you can edit any option to fine-tune how challenging each question is.
- Can I create MCQs from text instead of a file?
- Yes. You do not need a file to use the MCQ generator. Paste your text straight into the tool and it generates multiple choice questions from that content the same way it does from an upload. This is handy when you only have a passage, an article or a set of notes rather than a finished PDF or Word document.
- How many MCQs should a test have?
- Ten to fifteen for a chapter quiz, twenty five to forty for a unit test, and fifty or more for a midterm or final. The practical constraint is time: allow roughly one minute per straightforward recall item and closer to two for anything requiring a calculation or a scenario. Below ten items each question swings the score too far, so a single misread costs a competent student a letter grade.
- How many answer options should an MCQ have?
- Four is the convention, but three is often better. Research on option counts has repeatedly found that most four and five option items effectively function as three option items anyway, because one distractor is implausible enough that almost nobody picks it. A fourth option you had to invent to fill space adds guessing noise rather than difficulty. Write three strong distractors or write two.
- Do you need an answer key with generated MCQs?
- Yes, and it should come out of the same pass that wrote the questions. A key maintained separately drifts the moment you delete an item and forget to renumber, which is the most common grading error on paper tests. PDFQuiz marks the correct option as it drafts, and exports the student copy and the answer key as two separate files.
- How do you check if an AI-generated multiple choice question is any good?
- Cover the options and try to answer the question from the stem alone. If you cannot, the stem is underspecified and needs more detail. That single test, called the cover-the-options rule in the NBME Item-Writing Guide, catches most weak generated items in a few seconds. Then check that every option is homogeneous, judged true or false on one dimension, and that the correct answer is not the longest or most detailed choice.
- What are the most common flaws in multiple choice questions?
- The NBME Item-Writing Guide sorts them into two families. Flaws that add irrelevant difficulty include long or complex options, inconsistent numeric formats, vague frequency terms, None of the above, nonparallel options, complicated stems and negatively phrased lead-ins. Flaws that cue a test-wise student include grammatical cues, collectively exhaustive options, absolute terms such as always or never, a correct option that stands out, word repetition between stem and answer, and convergence.
- How do I make an MCQ test online?
- Upload the source material to an MCQ maker, set the number of questions and the difficulty, then edit and export. PDFQuiz reads a PDF, Word file, slide deck, image or pasted text, writes each stem with its options and marks the correct answer, and exports the test and its answer key as two separate PDF or Word files so you can hand out the student copy on its own.
- What is the best MCQ generator?
- The best MCQ generator turns your own material into fair questions fastest while leaving you in control of the wording and the answer key. PDFQuiz reads your document and drafts multiple choice questions with plausible distractors in seconds, lets you edit every stem and option, and exports to PDF or Word with the answers marked. Because it works from your file, the questions match what you actually taught.
- Can I generate MCQs from a scanned PDF?
- Yes, on a paid plan. A scanned PDF is a picture of a page, so the words have to be recognized before any question can be written from them. PDFQuiz runs OCR on those pages and then drafts the multiple choice questions normally, with 150 OCR pages included every 30 days. If a file has no text layer and OCR is not on your plan, the upload stops and says so instead of returning half a quiz.
- How many MCQs can you generate from one PDF?
- As many as the material genuinely supports, which for a ten page chapter is usually 15 to 25 questions worth keeping. Push past that and the generator starts testing detail nobody meant to assess, like the year in a footnote. Set the count deliberately rather than taking the highest number offered. Nothing caps questions per file; the real ceiling is your monthly character allowance.
- Why did the generator only use part of my document?
- Almost always one of three things. The preview on this page reads the first 5 pages only, so a longer upload looks truncated by design. Or a page range was left set from a previous run. Or the pages are scanned and OCR did not run, in which case the questions stop exactly where the text layer stopped. Check the page range first, because it is the quickest to rule out.
- Where do I get the answer key for the MCQs?
- It comes with the set. PDFQuiz marks the correct option while it drafts each question, and the answer key generator exports the student copy and the key as two separate files so you can hand out the paper without the answers on it.
