SBA question generator built for medical exams
Practise single best answers from your own slides.
An SBA question generator turns a lecture into single best answer questions: a clinical stem, one best answer, and plausible distractors that are not quite right. Recall Engine writes them from the pages you pick in your own PDF and links every answer and explanation to its source page. The sample below was built from page 3 of our public reference sheet. Open the sheet and check it yourself.

Single best answer · Question 1
p. 3A 34-year-old man has had fever and a deep ache in his left shin for 10 days. Three weeks ago he had an open fracture of the tibia. There is focal tenderness over the tibial shaft, the overlying skin is not red, and moving the knee and ankle is painless.
Which is the most likely diagnosis?
- A. Cellulitis
- B. Septic arthritis
- C. Osteomyelitis
- D. Osteonecrosis
- E. Stress fracture
Show the answer
C. Osteomyelitis
Focal bone tenderness is the local clue for bone involvement, and an open fracture is a direct route into bone. Painless joint movement argues against septic arthritis; skin without warmth or redness argues against cellulitis.
Built from the “Name the infected compartment” and “How infection reaches bone” tables on page 3 of a public sample reference sheet. This is a teaching example rather than clinical advice.

Frequently asked questions
Another question?
support@recallengine.appWhat is an SBA question generator?
An SBA question generator turns study material into single best answer questions. That is the format used in most medical exams. Recall Engine builds them from your own lecture PDFs and links each answer to its source page.
Can I generate SBAs from a PDF?
Yes. Upload a lecture PDF, select the pages, and Recall Engine generates SBA questions with answers and explanations. Both text-based and scanned PDFs are supported.
Are the generated SBAs accurate?
Every SBA includes a source page reference so you can check it against your lecture before relying on it. The output is grounded in your material but you remain the final authority on accuracy.
Is it free?
You get 50 credits free on signup with no card required. Credits are only deducted after a generation succeeds.
Can I practise SBAs without uploading a lecture?
Yes. The prepared question bank has SBAs and MCQs for all five years of medical school. Every question explains every option.
Can I use the SBAs for USMLE, PLAB, or my university finals?
The questions use the single best answer format that most finals and licensing exams use. That makes them good for rehearsing that style. They are built from your own lectures rather than a fixed syllabus. Treat them as targeted practice on what you were taught and use a dedicated bank for board-specific coverage.
How many SBAs can I generate?
Choose 5 to 30 questions per generation. Credits depend on how many questions you make and are charged only after a run succeeds. You start with 50 free credits on signup.
Does it work on scanned or handwritten lectures?
Scanned PDFs work because Recall Engine reads each page visually rather than relying on a text layer. Clear handwriting can work too. Messy or low-contrast scans are less reliable. Check the source page link on each SBA before you trust it.
Is this better than just asking ChatGPT to write SBAs?
General chatbots can work with uploaded lectures and draft SBAs. Recall Engine brings lecture selection, source-page references, saved questions, and review into one workflow. Compare both on your own material and check the answers against the source; neither approach guarantees accuracy.
