hello Ayush

i hope you are doing great and fine.

With reference to your query , I would like to say you that ews certificate is valid from finanical year which is generally starts in 1st april and ends in next year on 30th march . So you have to check the finanical year of form applying and financial year in which merit list come ,if same then you can go with same certificate else you have to apply again for it

Hope you found this answer helpful. Good luck for your future
