How Question Paper Builder Pro moves through a job, step by step. The run below is an example output, written from what this agent does. It isn't a live run on your data.
Sample input
Question bank CSV (id, question, marks, type, chapter, difficulty, options, answer, marking scheme)
Example output Illustration
You get: - paper-set-a.docx ... paper-set-f.docx and Markdown copies - answer-key-set-a.docx ... with marking scheme notes - blueprint-check.md: marks by section, chapter (with gap against your weightage) and difficulty - used-questions.csv to pass back with --exclude next time
Third-party costs are paid to those providers, not to us.
43/43 automated checks pass on Python 3.13.5 (standard library only); 18 cases incl. invalid input, duplicates and upstream failures. Not tested: opening the .docx in Microsoft Word itself (checked in LibreOffice); printing; banks in scripts other than Latin and Devanagari.
