Hello,

Yes, you can do 10th (Matric) from NIOS even after completing higher studies. NIOS allows learners to complete secondary education at any age.

Even if it is not in chronological order , it is generally accepted for competitive exams. You can mention your NIOS 10th marks when required. Most boards and universities accept this as long as you provide the certificate.

Steps you can take:

1. Enrol in NIOS secondary course (10th).

2. Complete the exams and get the certificate.

3. Use this certificate wherever a 10th qualification is mandatory.

Competitive exam authorities usually accept this, but make sure to check the specific exam rules for age and eligibility.

Hope it helps !
