Every course has a question genome
Upload the past papers you already have. qDNA reads every scanned page, extracts each question with its marks and provenance, and computes what actually recurs — topic frequency, Pareto coverage, and the lineage of questions that keep coming back in new clothes.

Pages are rendered in your browser and sent to the extractor in small batches. Your files are never stored on a server.
Or open a corpus we already extracted:
Genome map
Topics down, papers across. Cell density shows where a course spends its marks, semester after semester.
Question lineage
Near-identical questions cluster together, even when the numbers change and the wording is rewritten.
Pareto coverage
How few topics account for most of the paper — computed from your corpus, not asserted.
