What you need to look at is the path to your end goal; unfortunately this is a long one towards ENT surgery or Plastics surgery.
It takes around 10 years of training after university (in itself 5-6 years) to become a consultant in either (slightly longer for plastics). You will have to do most likely 2 degrees, sit numerous exams and be passionate about noses for the rest of your life. It is competitive, expensive and at times, depressing but nonetheless a rewarding and interesting career.
Consider doing some work experience to see if it's something you will like.
