Hi Rekha,

Certainly, if you qualify CUET in the year 2026, you can apply to B.Sc. (Hons.) Mathematics or Biology at DU (Delhi University), even though you completed your 12th Level in the year 2021. Delhi University does not have any upper age limit for undergraduate admissions and eligibility is based on having passed Grade 12 with the relevant subjects and qualifying to sit for the CUET in that admission year (2026). If you sit for CUET 2026 and get a good score, so long as you meet the subject criteria and percentage criteria for the specific course, you would be eligible for admission to government colleges, like colleges admitted to Delhi University.

Yes, you can. Age gap after 12th is not a problem for CUET-based admission.

As long as you meet the eligibility (10+2 with required subjects), you can apply for CUET UG 2026. DU admissions are purely CUET-score based, not on year of passing. So if you prepare well and score high in CUET 2026, you can get B.Sc Hons in DU (Maths/Biology) or any other central university.

Thank you!

Hello! Yes, you can definitely switch your career path and aim for a BSc  in Maths or Biology through DU by attempting CUET 2026. Delhi University admissions for BSc are based on CUET scores, and your 12th completion year does not restrict you, as long as you meet the eligibility criteria of having qualified 12th with the required subjects. You should check the specific eligibility for the course you choose Maths or Biology since some courses may require certain subjects at 12th. Focus on preparing well for CUET 2026, and with good marks, you have a strong chance of getting into a government college like DU.
