Hello Yamini!

The fill correct subject mapping error usually occurs when the subjects you have entered do not align exactly with the options or combinations expected by the counselling portal. For DU NCET counselling, the system is quite particular subject names in your marksheet must be selected exactly as they appear in the drop-down list during form filling. Sometimes, certain browsers or devices may not display the drop-down properly, which is why you see no subject option. Try using a laptop instead of a phone, clear cache, or switch to a different browser like Chrome . If the issue continues, contact the official helpline or DU’s NCET counselling support via email or phone—they can reset or correct your mapping. Avoid submitting the form with wrong mapping as it may affect eligibility.

Thank you.
