I think I will score around 500 in neet 2020 so which govt college I may get in Maharashtra from open category?

Hey,

As per the previous year's trend, the lowest qualifying marks required for getting admission in the topmost and eminent Government Medical colleges in 12 districts of Maharashtra ( i.e. Baramati, Jalgaoan, Nagpur, Pune, Akula, Aurangabad, Mumbai, Nashik, Lator, Miraj, Gondia and Chandrapur) for MBBS and BDS were 560 and 527 respectively through the Home State quota.

Hence it's quite obvious that in this year the cut-off marks will definitely be increased by the Commissionerate of the Common Entrance Test (CET), Maharashtra. So I think now it becomes crystal-clear for you also that if you're a General-UR aspirant, it's just impossible for yo to get admitted in all those renowned institutions with this marks and percentile.

It's okk, don't need to worried. You can also check Careers360 college predictor tool for your own mental satisfaction in this context:
