EWS :- that is Economically Weaker Sections have the reservstion of 10% as being decided by the Government So according to a survey almost 35% of people in india are under EWS so this 10% reservation will not play a very major role according to me 

moreover with 96 marks your percentile will be somewhwre between 92 to 94 and rank would be somwhere about 58000 to 68000 

First of all congratulations for scoring such a high percentile 90 percent or more than 90 % percentile is always a good accomplishment you can get some of the Nit according to your percentile and category and stream that you are looking for plus you have ews that will help you a bit
