I've been looking at some universities abroad (I'm from Norway) like in Hong Kong (HKUST), but the academic staff to student ratio seems dreadful compared to others with 1:23. Still, people seem to think it's a really great place to go. Also, it's ranked 19th in the world in the course I want to take, Mechanical Engineering, despite this.
So, my question is, how much weight should I put in this ratio? Will it impact my education greatly when the ratio is so high?
