Dear aspirant

I hope you are doing good.

As per your query , I would like to inform you that ews reservation was implemented on 7 january 2019 to give benefits to the students who belong to general category and do not have income more than 8lakhs from all the asset. 10 percent seats are reserved for ews category , by this you can assume how much benefit you wll get among rest of non-ews students . Variation of rank is different in different exam due to difference in application number

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