So this is an update post of my earlier enquiry regarding student discount on Apple devices - https://www.reddit.com/r/NIOS\_Students/s/8w8VzIPtij
So that I tried to get verified in unidays which apple uses to verify students
After multiple tries to get verified using id card and and fee receipt and whatsoever documents didn't got verified until I submitted an admission status page screenshot in which I didn't had much hope but surprisingly it got verified
So yeah now I can get discounts on Apple products as well as along with many brands which provide students discount
This is for the people who want to avail this discounts
So when you get in unidays page first of they ask to sign in which only requires your email and any otp after that search for the institution in which you might find many national regional centres name, in which you have to find THE NATIONAL INSTITUTE OF OPEN SCHOOLING Noida (specifically search this name only)
After this they might ask for student email, skip that and go to the page where they ask id card or enrollment document something like this
There just submit the admission status page screenshot under document which you can get from here -https://sdmis.nios.ac.in/registration/check-admission-status
And wait for 24 hrs, you will get an email that it's verified or not
And that's it, it worked for me, it might work for you also
