hi there ,

As per your query ,

Whether you are from ISC or CBSE or State Board, you have to give only IELTS and get admitted in any Canadian university . The advantage of being an ISC student here is that you are more likely to be accepted in a particular university than the others.

Hope you understand , in case of any issue you can comment here and also  make a new query for the same.

Thank you and all the best.
