How a CBSE exam generator fits into board exam prep

Upload NCERT chapters, class notes or slide decks in PDF, DOCX or PPTX.
Photos of printed pages are read with text recognition.
Get multiple choice, true/false and short answer questions with explanations.
Review missed questions and export to PDF or DOCX on a paid plan.

Frequently asked questions

How many practice questions should I do for a CBSE board exam?

Does DeckOwl follow the CBSE syllabus automatically?

DeckOwl does not load a syllabus on its own. It builds questions from the material you upload, so using official NCERT chapters or your school's notes keeps practice aligned with what you are studying.
