hello,

If you are unable to generate your RUC code, i would suggest please go to the official website:

https://finalmdmsmch.aiimsexams.org/Login#!

Log in there, fill all you required details. if your application is accepted, then you would be sent a confirmation mail from Aiims along with you RUC.

If you are still unable, you will have to wait till AIIMS opens the portal for RUC generation.

Hope it helps.
