Hello Utkarsh,

Since you fall under GEN-EWS category, so you can take admission as per your EWS rank. The 2019 JEE Main cutoff for GEN-EWS category is 78.21 percentile. So if you have cleared the cutoff as per your category then you are eligible to get colleges like NITs,IIITs,GFTIs. To get these colleges you have to go through JoSAA counselling process. For private colleges or other government colleges you have to attend their respective counselling processes and see which branches are you getting. If by any chance you don't get a seat through JoSAA counselling but on the other hand if you are JEE Main qualified then you can apply for CSAB counselling through which you can get seats in NITs,IIITs,GFTIs,SFTIs.
