Dear Synran, there are still reports of technical issues. AIIMS hasnt given any technical resolution for this. We understand it gets tense and irritating to not be able to fill up the form.inspite of facing the same issue for days together but at this point in time, this is the only step. Clearing the cache, browsing history, restarting the system and relogging in. You still have time until the 12th so please keep trying.
