The expectation is that you'll work about 40 hours a week, i.e. full time job hours. If you sleep 8 hours a day, then that leaves you with 8 hours of free time Mon-Fri and 16 hours of free time at the weekend. Yes, that's a lot of free time if you literally have nothing else in your life. Do you really not have any hobbies or interests? You don't do any sports, you don't do anything musical, you don't do anything creative, you're not involved in any volunteering...? I mean, some people don't, but when people talk about how busy they are at university, it's normally because in addition to their basic 40 hours a week of work they are doing a load of other stuff too, rather than because uni work is filling every waking hour.
