Which ion is primarily responsible for the plateau phase of a cardiac action potential?
Pick the right format
Which question type fits what you're studying
From one upload — PDFs, slides, docs, video, audio, YouTube, images, or pasted notes — ClassFactor can build any of these. Reach for the format that matches your goal.
Check you truly understand
Multiple-choice
When recognition isn’t enough, MCQs with plausible distractors force a real decision — the wrong options are the mistakes your material is trying to correct.
Cover a lot, fast
True / false
When you’re sweeping a chapter for weak spots, quick true/false calls surface the exact statements you only half-remember before the exam does.
Practise explaining
Written / free-response
When the test rewards prose, open prompts make you produce the answer in your own words instead of picking it off a list.
Apply it in context
Clinical-case
When facts have to become decisions, a vignette sets the scene and asks you to reason to an answer — built for med, health, and any applied subject.
How it works
Generate, answer, and grade yourself in under a minute
Generate a question set
Point ClassFactor at your material and choose the formats — MCQ, true/false, written, clinical-case, or a mix. Each question is written straight from your source, with plausible distractors on the MCQs.
Test yourself and get it graded
Work through the set like a real test: commit to an answer and ClassFactor grades it on the spot, showing the correct response and a rationale cited back to your own page or timestamp.
Send your misses back to review
A judge model keeps weak, duplicate, or trivially-easy questions out — and the ones you get wrong flow into your FSRS queue, so they come back until they stick.
Question types
Mix all four in a single set
Ask for one format or blend them — a set can run MCQ, true/false, written, and clinical-case side by side, each written from your own source.
Multiple-choice (MCQ)
Four-option questions with distractors built to test real understanding — the wrong answers are the plausible mistakes, not obvious throwaways.
True / false
Fast, high-volume checks that surface the exact statements you half-remember, so you find the gaps before an exam does.
Written / free-response
Open-ended prompts that make you explain and reason in your own words — the kind of recall that short-answer and essay exams reward.
Clinical-case
A scenario or vignette sets the stage, then asks you to reason to an answer — ideal for med, health, and any applied subject where context matters.
Which ion is primarily responsible for the plateau phase of a cardiac action potential?
A good multiple-choice question lives or dies by its wrong answers. Throwaway options you can eliminate at a glance teach you nothing.
ClassFactor writes distractors that mirror the real misconceptions your material is trying to correct — so choosing the right answer means you genuinely understand it, not that you spotted the odd one out.
Plausible distractors
Wrong answers that make you think
Every MCQ is grounded in your source, so its options reflect the genuine confusions in the topic. That is what turns a quick quiz into real practice — and it is why a judge model drops any question that is too easy to be useful before it reaches you.
Quality you can trust
Questions that match your course, not a generic bank
Distractors from your own source
Every question — and every wrong option — is built from your uploaded material, not a generic bank, so the distractors mirror the real confusions in your course.
Cited to the exact page
Each question links back to the page or timestamp it came from, so you can jump to the source and check the answer in one tap.
Filtered before you see it
A judge model removes vague, duplicate, or trivially-easy questions up front, so your set stays tight and worth your time.
Yours to refine
Edit any question inline, or thumbs-down one to remove it and prompt a better replacement. The set bends to how you study.
Who it's for
Built for the way you actually study
Med & health students
Turn dense lectures into clinical-case vignettes and board-style MCQs that make you reason, not just recognize.

FAQ
AI question generator, answered
From the same uploaded material, ClassFactor generates multiple-choice (MCQ), true/false, written/free-response, and clinical-case questions. You can ask for one type or a mix. Flashcards are also available and are covered on a separate page. Every question type works from PDFs, slides, docs, audio, video, YouTube links, images, or pasted notes.
ClassFactor writes plausible distractors — wrong options built to test real understanding rather than obvious throwaways you can eliminate at a glance. Because the distractors are grounded in your source, they mirror the genuine misconceptions the material is trying to correct, so getting the question right means you actually understand it.
Each question is grounded in your own source and cites the exact page or timestamp, which keeps it faithful to your material. A judge model filters out weak, duplicate, or trivially-easy questions before they reach you, and you can thumbs-down any question to remove and improve it, or edit it directly. As with any AI, we recommend a quick review for high-stakes topics.
Clinical-case questions present a scenario or vignette — a patient, a situation, a set of findings — and then ask you to reason to an answer. They are built for med and health students and for any applied subject where you need to apply concepts in context rather than recall an isolated fact.
