Hi.

1) Private colleges do not participate in state counselling in this case, MBBS Admission Counselling conducted by state of Kerala, which is based on marks obtained in NEET Exam. Incase you wish to pursue MBBS in a private college then depending on the college you opt for they have their own admission procedure. For instance, some might consider NEET Exams some might not. So for better clarification, you can provide the college you wish to opt for so I can let you know its admission procedure.

You can see the list of private college at THIS PAGE

2) You can use the College Predictor for State-based counselling depending on your credentials.

BEST OF LUCK.
