how many marks are required for a OBC candidate in neet for securing government medical college?

Dhanish, you havent mentioned the State you belong to. This is important because every Medical College allots 15% to All India Quota and the admission to remaining 85% seats are conducted through State Counselling. And the cut offs differ for each Counselling and each State. For example, Delhi  Bihar and Haryana have higher cut offs than the rest of the States. But in General if you belong to OBC Category, you will need nothing less than 550-575. Now cut offs change every year depending on various factors. So please do help us with the State you hold the domicile of.  For guidance regarding counselling and admission, you can use our MBBS Companion: https://www.careers360.com/mbbs-companion
