hello,

Not only for karnataka , there are few more changes in the fee structure for other Southern States like Andhra Pradesh, Telanagana etc.

But the government strictly changed the fee structure to 

A Category :

Govt- 10,000per annum

private- 50,000 per annum

B category , its 11lakh per annum

This is the information Found from official NEET website, nothing like huge difference, even the number of seats increased as vice versa it happened with the fee structure also.

hope this helped you,

Thanks & Regards,

SIRISHA SANATHA.
