hello Reddy

I hope you are doing good. As per your query , I would glad to inform you that sastra university admissions are not totally based on jee main score .

Around majority of seats which is around 70-75 percents seats are filled through by considering boards and jee mains marsks. Admission on remaining seats are given on boards score only . But applications are very high in number so cut off goes very high around 95percent every  year. I do advise you give your boards percenatge because to be very honest at your percentile chances of getting seat through jee main is low

Hope you found this answer helpful. Good luck for your future
