Which is the most demanding degree abroad today?

Hey Charitha. How are you doing?

So there is no specific answer to your question as we can not claim one degree to be the most demanding one. Let's suppose even if we have a degree that is the most demanding one, it is not necessary that it would be relevant to you as well. For instance, if medicine is a field that is the most demanding one in a specific country and you have no interest whatsoever in the field, it's definitely not the right one for you. I can tell you which place is the most suitable one for which course like the USA is considered best for medical and engineering and the UK is considered the right place for business administration and management, France is known for the fashion field and similarly, various countries have different fields which have the most number of universities and employment opportunities over there. 

Why don’t you tell me more about your academic background, extracurriculars, and interests, and maybe then I can find out which course would be the most appropriate for you and which country you can consider for the same.
