I have applied for UGC NET Examination December,2014 for Assistant Professor, which will be held on 28.12.2014. My Roll No. is 12870734, Subject: Computer Science and Applications (Code-87), Centre applied: University of Calcutta (Code-12). i.e., my co-ordinating Institution is the University of Calcutta. But when I am searching the Centre wise seating allotment for NET Examination (through 'www.caluniv.ac.in', then 'news and announcements' then 'UGC NET Examination, December, 2014' then 'Centre wise allottment for the NET Examination, December, 2014' shows "The file is damaged and could not be repaired". That is, loaded file can not be opened. Who will be responsible for that? Is the University of Calcutta can take the responsibility for the damaged file? Why they loaded the damaged file through the internet? Please take necessary action as required. I can't appear the Examination for that irresponsibily of Calcutta University. Please inform me what action should be taken for this irresponsibilty or damaged file entry in the internet which should not be used to Examination candidates.
