Hello,

If you have forgotten your 2017 high school roll number, you can find it in these ways:

1. Check your mark sheet or certificate:
   Your roll number is printed on your 10th class mark sheet and passing certificate.

2. Contact your school:
   Visit or call your school where you studied. The school keeps student records and can help you find your roll number.

3. Contact your education board:
   Go to the official website or regional office of your education board (like CBSE, UP Board, etc.). You can request your roll number by giving details like your name, father’s name, school name, and year of passing.

4. Check old admit cards or documents:
   If you have your old admit card, registration card, or any photocopy of documents, your roll number will be mentioned there.

Hope it helps !
