Hello, aspirant

No, there are no penalty fees if you quit the course.

NEET is India's biggest medical entrance exam which includes various courses. The cutoff and the competition are getting higher day by day. Students usually give 2-3 attempts and some of them also give 5 attempts. They usually prepare while being in other graduation courses. In some colleges, teachers and professors appreciate this and understand students' situations in my case I was doing my BSc and also preparing for NEET and when I told my professors about this all of them were there to help me.

According to me, you should give it one more chance and work hard and hope you will get your goal soon.
