Hello Aspirant,

No as the marks scored by your sister is not enough for getting a government seat as this year the cutoff for medical colleges has increased really high so your chances are very low. If your concerned about government seat then I would advise you to attempt NEET 20201 and try scoring above 550+marks as per your category for having good chances of securing a seat in a government college. Else you could still get seat into private universities.

Hope this helps

Good Luck
