Hi, 

Frankly, 348 is a less score for getting a seat in any government Medical college in India. But still the we can't say with much authority whether you will get a seat or not. Only when the official notice regarding cut off is released, we can check the rest thing. But still I believe that with this score you will definitely clear the minimum cut off. For now, I will ask you to keep calm and wait for the results. But if you are really into getting a government seat, I will suggest you to continue your studies and try to score above 550 next time. That's a safe score for getting into government college. 

Good luck!
