DGCA Computer Number

good morning all, I need help getting my computer number, so basically I have completed my 10th(IGCSE) Cambridge abroad i’ve also completed my 11th(AS level) cambridge but i didn’t complete my 12th since it’s not required in the county i live in. I joined university majoring in Aeronautical engineering and i want to become a pilot, how can i proceed further without 12th mark sheet, also i’ve completed GED but when i asked AIU they said it isn’t equivalent to 12th. my question is 1) How do i get board verification for 10th? 2) Do i need to apply for equivalency with AIU for my 10th result ? 3) can i use my university grades as 12th equivalent since i studied physics and calculus that is more advanced than 12? please help me im lost, thank you
