Hope you are doing well Maheshwar!
The cutoff for private college varies across different colleges and courses. Therefore you must mention the name of college and course so that I can check and tell you.
Otherwise you can also the check the previous year merit list from the official website of college and understand the specific cutoff criteria. You must try to attain good percentage likely more than 80% in order to maximize your chances of admission.
