Hi aspirant.

Let me put this to your information that the cutoff depends on several factors and varies for different category. Therefore it is required to know which category the candidate belongs to in order to give you more precise information. There is 85% seats reserved for state quota in all the private colleges. Since you haven't mentioned your category let me update you with the cutoff for general category to these seats of some major private colleges in Karnataka. However the cutoff will be much lower for other reserved categories:

AJ institute of medical sciences Mangalore - 427

Father Muller institute of medical education - 471

JSS medical college Mysore - 501

Al Ameen Medical College Vijayapur - 396

Hope this helps.

Good luck!!
