Hi Nihai,
No. Definitely not. Although the exact number of seats filled up varies from one year to another, still not all seats are filled up.
Yes, certain courses like CSE and ECE are the most popular ones and they get filledup quickly while others take much more time as students wait for the exact count, and check the seat matrix after first round in the colleges.
So a handful of seats are only filled up after the first round of counseling.
Hope this helps!
