NHH is one of the underrated universities that most people do not know about. For starters, tuition used to be free there. One of the reasons it was my top choice, but then it was also the best Business School in Norway. The faculty was top notch and the learning curriculum was pretty unique with ample free time, and freedom, yet required great application too.
Another reason was that it offered students amazing opportunities to study abroad (Double Degree program and CEMS (International Management) program. The university gave students the freedom to pick their own courses, fields, and specializations. Another attractive part of my experience was the 100 subcommittees that were present at the university which gave you a chance at not just professional growth, but experience interacting with other internationals and Norwegians, which was a great deal for someone travelling abroad for just the second time. You could learn photography or graphic designing and be a part of a family of a sort.
I am sure there would be better universities, but NHH is still amongst the best and gives you the exposure to stand out and still mix up with everyone.
