Gap Year

I would like to do a gap year after finishing university.
It is usually done before but I prefer to focus on studying first. For this reason I think it is better that when I finish studying the race, I will go to do a master for some countries.
I would like to travel to Finland and Sweden, as they are two very advanced countries technologically and socially. But I would also like to travel around Canada and the United States.
But I still have a lot of time to think about it and plan for more detail in my gap year.
