Turn a lecture PDF into SBA questions
Turn the PDF pages you pick into single best answers tied to each page.
PDF to SBA questions means turning the pages of a lecture PDF into single best answer questions: a clinical stem, one best answer, and distractors that are close but wrong. Recall Engine reads each PDF page as text and as an image so tables, figures, and scanned slides count. Every question links to the page it was written from.

Single best answer · Question 1
p. 3A 9-year-old boy has had a fever and a painful right thigh for three days. There is focal tenderness over the lower femur and the knee moves freely without pain. A plain X-ray of the femur is normal.
Which is the best interpretation of the normal X-ray?
Show the answer
B. An early X-ray can be normal in bone infection
Focal bone tenderness in a child's long bone points to bone infection. The imaging row warns that early X-rays may be normal. Painless knee movement argues against the joint space.
Built from the “Name the infected compartment”, “How infection reaches bone”, and “What each investigation contributes” 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.appHow do I turn a PDF into SBA questions?
Upload the lecture PDF, select the pages you want tested, and choose SBA as the format. Recall Engine writes the questions with answers and explanations. Each one links to its source page.
What makes an SBA different from an MCQ?
An SBA gives a clinical stem and several plausible options where one answer is best. A quick MCQ checks one fact with one correct option. See what is an SBA question for the format in detail.
Does it work on scanned or image-heavy PDFs?
Yes. Each PDF page is read as an image as well as text. Scanned slides, tables, and labelled figures can all be tested. Clear scans give better questions than blurred ones.
Are the SBAs accurate?
Each SBA links to its source page so you can check the answer against your lecture. The questions are a study aid built from your material. You remain the final check on accuracy.
Is it free?
You get 50 free credits on signup with no card required. Credits are charged only after a generation succeeds.
