Yes, you can get admission to government BCA universities with both marksheets, as long as they meet the university's eligibility criteria. Your state board marksheet will validate your overall 12th completion, while the NIOS marksheet for Mathematics as an additional subject fulfills specific subject requirements for BCA, where Mathematics is often mandatory. Ensure both are officially recognized and submit them during the admission process. Confirm with the university if they accept this combination before applying.
