Hey there!

In order to have a career in dermatology, you will have to pursue MBBS followed by specialization in dermatology.

You will have to give the NEET entrance examination which will provide you a seat in a government or private college for MBBS.

The fee structure varies from college to college, for the same. So, you will have to make a list of colleges that you wish to attend and look up at the fee structure for the same.

Hope this helps. Good luck!
