The work is not impossible ,but a bit tough, but if members from each state take the job of forming list from their state, then i think it can be done easily.
from last year,AICTE has made it compulsory for every college to show a disclosure on its website containing details of last years admission process, mode of admission and details of scholarships, along with the distribution of seats in various branches and also the details of the faculty and facilities in the college.
so i think viewing that disclosure will make it much easier work, we just need to look for a file 'Mandatory Disclosure' on the site, and i hop it will provide most details we need.
