The new structure thought process is, elementary knowledge is provided till the 10th (High School) then specific ones in Physics, Bio, Chemistry, and Maths are moved to the Higher secondary level.
what elementary knowledge?
here we study chemistry and physics and mathematics for 4 years in high-school
those basics are taught in primary school
1st year
math, science, Quran and Literature
2nd year
math, science, Quran and Literature and theology (not very advance more like stories about prophets and ...)
3rd year
math, science, Quran and Literature and theology and social sciences
4th year
math, science, Quran and Literature and theology and social sciences
5th year
math, science, Quran and Literature and theology and social sciences
6th year
math , science, Quran, Literature, theology, social sciences, Thinking and Research, Work and technology
then its junior high school and still basic if you are not attending special schools for gifted if you go to those schools your Math, science and Literature would be a lot more advanced
7th year
math , science, Quran, Literature, theology, social sciences, Thinking and life style , Work and technology, art and culture, Arabic, English
8th year
math , science, Quran, Literature, theology, social sciences, Thinking and life style , Work and technology, art and culture, Arabic, English
9th year
7th year
math , science, Quran, Literature, theology, social sciences(Geography ,History and Social science), defensive studies , Work and technology, art and culture, Arabic, English.
then its Senior high school. you are divided into 3 group based on your interest majority go into theoretical sciences some into industry studies and some into jobs their study would be different the majority that go into theoretical science for 4 years and are divided to for group of Mathemathic , experimental science and Literature and Islamic studies and in this 4 years they don't study basic any more they study , chemistry , physics, algebra , statistics , biology , Geology , Geometry , calculus, statistics, ecology ,discrete mathematics,history , geography, philosophy , sociology , logic art , ethics , fiqh ,.... depended ion the field they choose.
thats why it was strange for me when you say you are going to study basics till last years of high school, here we study those specific to our fields in detail for 4 years
