Hello aspirant,

Hope you are doing well. The councilling schedule is changed and you need not to cancel your registration once you have done it if you have not selected the eWS category in the beginning then you have the option for the correction in the form so that time you can change it to ews category because if you have paid the councilling fees and now if you cancel it then your fees will not be refunded so better option to go for the correction. 

Hope this helps

If any queries feel free to ask

All the best!!

Regards
