My national school system consist of primary school, high school and then further education.
primary school goes from 1st to 9th grade, and people usually begins school at the age of 6, tough it can vary +/- 1 year. After 9th grade, one has achieved the legal amount of education, yet one can choose to go to grade 10th grade as an extension to primary school, continue to high school or educate them to certain proffesions like lumberjack, cook and similar.
High school consist of 3 main branches: General, technical or buisness, where technical focuses on science and technology, buisness on buisness and general on humanities and some science. This is a three year period, and subjects in the high school are ranked from C to A and determine how long one has that subject (from 1 to 3 years). After high school, one is eligible to university and college.
I am personal finishing technical high school and plans on starting on my bachelor in mathematics this september, then my master and finally my Ph.D. Tough, I must say my math classes leaves a lot to be desired, mainly since they are more calculation than math.
