Dear Aspirant,

With 75 percentile you have not cleared the cutoff of JEE Mains 2020 for GEN EWS and hence getting admitted into NITs and IIITs will not be possible and as for the other part you can get into some descent private engineering college like SRM,DIT(Pimpri),MIT WPU, Bennett University,etc.will be some of your top choices.So Best of luck.
