Hello dear
Ews category is included first time in jee mains and we don't know the trends and cut offs for this category.
But if we consider statistics ( only 10 % reservation ) than it is difficult to get a good college ( like nit and IIITs ) ; you may get state government colleges or good private colleges .
So I would suggest you to take part in counseling and fill your preference wisely.
Good luck.
