The Universidad de Sevilla requires you a lot, so you need to be prepared to suffer at some (many) points. At least, that is my experience in one of its schools, the ETSI, where I study Aerospace Engineering. Indeed, the degree I study is not easy, but some subjects have more difficulty than they should, so they can make you get anxious. But overcoming these difficulties can get the best version of yourself. Also living in a city with so much life and joy as Sevilla can help you disconnect when you need it.
