It is difficult for you to get an admission for MBBS in a government college based on your NEET score. You can go for paramedical courses. Good private colleges provide you with a good environment and proper teachers. You can take admission in one of them. If you don't get a branch of your choice, go for another college.

Other than MBBS, you can go for other courses related to biology like Zoology and Botany as they are in demand in the era.

Yes it is possible, but you will get admission in only private college through management quota.
