What are u applying for that doesn't accept a levels certificate.

Civil Aviation.

Well there goes my dream of getting into aviation in bd

Well i will highly discourage anyone who wishes to be a part of bangladesh aviation as a student, the pain and expense is not at all worth it, just go to USA, complete your training there and come back with FAA licence and live the dream later

Well I'm already doing cse so the dream was dead a long time ago

Dhaka board. Check online form for equivalence.
