If you are from the home state then you can get ece till about 1130 ews rank on the other hand if you are from other states then ews rank around 650 will be required but you should note that I have mentioned the opening and closing ranks from the josaa website that too the latest one's but this years closing ranks does not indicate the cutoffs for the future it just gives a brief idea of whether you are in contention to get that branch or not it is no where a compulsion that you will get that branch or not.=
