I’ve done three courses and heard a lot from various students from different courses. It really depends on what you want to take and what you are looking for. For example, law bachelours is a really hard, and you will definitely sweat, but, after you leave, you will be more than able to handle everything that comes at you. Also in that regards, it is hard to get the older professors to actually hear advice and improve. They don’t care. Other ones like physics and Informatics, professors really love doing what they are doing and want to help you in any way they can, while also being open to feedback. Of course this is a generalisation and some outliers appear in both scenarios. But that is the overall deal with it.
In regards to student support from the institution, for me, when it’s email, Skype, phone, etc… (remote basically) they just want to move on and finish handling your case and needs. But if you go there in person, they are really kind and helpful.
Some things are really old and don’t receive an update for years, but, it feels like in the past years, the university has tried to improve the installations and make good quality of life improvements for everyone.
