I was NOT able to fill the Prelims 2017 form which had its deadline on 17 March 2017, 1800 hrs. There are many candidates who have not been able to fill it and a loss of attempt will be equivalent to a whole year's loss, there will be a break in middle and the flow will break Plus we'd have to wait for a year to learn about the mistakes committed.
We are planning to together go to UPSC on Monday and present a joint application so that there can be some action taken and the deadline could be extended. It will help if all the people sharing the same concern go together. We are communicating on WatssApp Group [link to join https://chat.whatsapp.com/05nWgLsxoWMIbpcsr7VMaC]
