Is it difficult to get a master degree in dermatology? Should I drop out of school

Actually, the problem lies with you. It depends on whether you want to study. Studying medicine is very popular now. Generally speaking, you are not afraid of not finding a job when you come out. Why don't you choose clinical? If you don't like dermatology, you can study first, and then transfer to another department, and work hard to get a good grade in the exam. You can ask to transfer to another department. I personally don't agree to drop out of school. Anyway, it's good to continue studying. I didn't want to drop out of school at the beginning, and I regret it, but if you really don't want to study, there's nothing you can do.
