If you're talking about med, after you finish your degree, you work. You sit exams for specialties while working (as far as I'm aware). So you'll be in university for 5-7 years.
As a year 11 student, probably best to spend minimal time on BoS asking hardly relevant questions and instead study.
I will personally be in university for 8 years all up (assuming I don't fail anything) and I enjoy it. Partly why I chose to continue studying was because working 70+hours a week in an office and getting minimal breaks doesnt sound appealing to every 20 year old. A lot of med people also do nasters (again, while working) and PhD (depends, sometimes while working but that is tough).
Final point, if you genuinely dislike learning new things/studying, you won't like university long term.
