About CBSE PYQ
CBSE PYQ is an independent, free Class 10 practice library that organises previous-year Maths and Science board questions by chapter, topic, marks, year and paper level.
Where the questions come from
The library is compiled from CBSE question-paper and marking-scheme PDFs. Each record retains exam metadata such as year, month, marks and level. Solutions are transcribed from the corresponding marking schemes and formatted for clear web reading.
How the library is produced
Document extraction and initial classification are assisted by software. Deduplication identifies repeated questions, and a review workflow is used to correct text, notation, chapter tags and figures. The production build can publish only questions explicitly approved in that workflow.
Independence
CBSE PYQ is not affiliated with, endorsed by, or an official service of the Central Board of Secondary Education. “CBSE” is used descriptively to identify the examination source.
