Despite of my suggestion yesterday, let me be nostalgic for a while.
For historical reason, I had six years in the medical school - the first of which was called the "pre-medical year", when we were under the Faculty of Science by administrative regulation, and we studied traditional science subjects (physics, chemistry and biology).
Isn't that a waste of time ?
We all thought so at that stage.
But no in retrospect. I took a course on human biology in the first semester and was well-fed on the evolution of skeleton; I took microbiology in the second half of the year. There were also courses on organic chemistry (with some relevance to pharmacology), food chemistry, psychology, Chinese, and physical education.
Yes, what really matters is whether we (alas, students) make a good use of the time. Planning and administration merely plays a small role.
PS. If you still see no value of them, there was at least plenty of spare time for us to pause and think and enjoy university life.
As Zhuangzi (莊子) said: The use of useless (無用之用).
