Yes you can indeed

Under Mukhya mantri medhavi chhatra yojana the application date will end on 15 June 2021.

So if you have already registered under this scheme and have filled the form. Then at the time of admission in undergraduate course the institute will verify this form filled under MMVY.

However no information is given regarding what will be the procedure if admission is not taken in valid time. Whether the students need to register once again or they need to use the same login ID and password each time and get the benefit of this yojana.

Since this scheme is for helping students from low income family to pursue higher education so one can hope that under this scheme students would be allowed to use their same ID for admission in college even after passing of valid time, or the students are allowed to register again .
