<p>Let me test my understanding.</p>
<p>You have done grade 9th and 10th in an ICSE school and for 11th and now 12th you are enrolled in CBSE school. So I don’t see a problem with that. In each grade, irrespective of the Board you would have appeared for the final exam and that is the Mark sheet that needs to be sent. And all these will go through your current School’s concillor. The current school should have no issues with attesting your 9 and 10 Mark sheet as you were admitted to CBSE on the basis of those.</p>
<p>High School means grades 9/10/11/12.</p>
