not able to proceed further in the application form after getting login id. not able to fill course applying form column... please help

Dear Lakshay, IPU hasn't released their online applications as yet. That is the reason though you have been able to register yourself, you aren't able to login. Because there is no application released yet, you are unable to fill in anything there. It is not a technical glitch. It's just that you registered a little early. The online applications for IPU CET will tentatively be released in the months of March/April depending on the course you want to take up.
