From place to place you’ll see a lot of variation in the total cost of getting a degree at university; this variation will also change a lot based upon the quality of the education and the policies of the government. In countries like the USA, the government exerts little cost control, while in countries like Sweden, Scotland and others you’ll have to pay very little, although this depends a lot upon you being from that country to receive the benefits.
Higher education can cost a lot but at the end of the day, somebody with a degree will typically more than make up the cost of their education in the additional income they will earn over their lifetime. This is true in every country, so no matter what the level of affordability of high education has in yours you can still get tremendous value out of the experience of going to university.
