Dear aspirant,

According to previous years cut off ranks analysis which is subjective as cut off ranks change every year depending upon a no of factors such as no of applicants etc etc so nothing can be predicted with 100% sureity last year from general category cut off rank was 249 against 412 marks so acc to previous years cut off rank you might not have a chance , and as for ews quota it is implemented from this year only we do not have any previous years data regarding it to predict rank, so again you  might/might not have a chance nothing can be predicted with sureity untill merit list for this year comes out with ews implementation

Hope this helps.
