Hello student

It's difficult to predict the exact possibilities of admission. It depends upon the cut-off. It changes every year. It depends upon a lot of factors such as the exam pattern, the number of students appeared, the number of students qualified, the highest score, whether you belong to any category or not.

However, with 75% marks in HSC Maharashtra state board  and 120 marks in NATA 2020, you should get admission in good private college, the chances of getting admission in government colleges seems low. To get admission in government colleges you need to score above 150. This data is based upon Last year's cutoff.
