I would imagine that is a wider set of topics than most would be taught. Certainly a great deal wider than I got.
They were split with half of each school year devoted to each topic, cannot say why we had so many subjects, but I have read before that Catholic schools were known for this.
I remember where some secodary schools had general science we had to do all 3 seperately and then choose 1 for our final 2 years, same we learnt german and french
In the forst 3 years we had classes in
English lit, english lang, physics, chemistry, biology, home economics, typewriting, german, french, history, geography, art, religious education, PE, maths, humanities, music and drama.
Im the last two years it was reduced to 6 with PE and religious education madatory on top of that.
