Hello,

If you register for the ISC Improvement Exam from a different school rather than the one where you appeared for the main ISC exam, you can consider following:

1. Number of Subjects : You can appear for one or more subjects , depending on the subjects offered by the new school.
2. Full Improvement : You may need to take all subjects again if the new school requires a fresh registration.
3. Board Approval : CISCE rules allow subject-wise improvement, but confirmation from the new school and the board is necessary.
4. Practical Exams : Subjects with practical components may require fresh assessments.
5. School Policies : Each school has specific rules regarding external improvement candidates.

Hope you find it useful !
