In the educational system that existed in Sri Lanka when I was growing up, students had to decide in the eighth grade what direction their future education would take, Since I knew I wanted to do physics, I chose to go in that direction and the rest of my education consisted of heavy doses of physics and mathematics with absolutely nothing in history, geography, literature, and social studies.
Naturally, this created huge gaps in my own knowledge base that later in life I have had to fill in as best as I can on my own.
This is not entirely a bad thing. One benefit is that I have not developed a hatred for the omitted subjects that those who have had heavy doses of formal education sometimes get. I actually like history and read about historical events for fun. And as I get older, I find that I know a lot of recent history by default, as I have actually lived through events that my children must learn about from history texts.
