Hey Aspirant

Here is not a huge difference between general category and obc, the thing is that there are 4 to 7 seat are kept in every government college for obc so chances of getting Admission in that is high for obc category , if you get 465 to 510 in neet you will get government medical college definitely.
ST/ SC/ OBC  400 minimum marks for government colleges.

For private colleges you have to score atleast 300 in neet , If you score more than 400 in neet then you can easily get private colleges in mumbai , Delhi and other cities.

Hope this will help you!
All the best!
