Dear Sanchita,
As you are aware that USER ID and Passward are alloted to first 1500 students only. But don't loose hope as there are many cases where students who have applied before in waiting list and who have also been alloted User IDs will not be taking classes for the simple reason, that after results many student who had thought they would pass have failed to do so. I have come across to 4 - 5 students of this nature myself. So you try to remain in touch with VG sir's staff and if possible discuss your issue with VG sir in personal.
Best of Luck........!!!
