What do you mean by "Honors"? Sign up? Do you mean you can choose which subjects you want to study?
Here every subject is mandatory. I study algebra, geometry, chemestry I and II, phisics I and II, biology, portuguese, redection, literature, english, spanish, history of art, music, performing arts, hystory, geography, phylosophy, sociology, physical education, but everyone does private classes in the afternoon, of languages (english (mainly), german, french, spanish, etc. I have already done japanese
), some kind of sport or academy, music classes, etc. Who doesn't have money to pay private classes have the option to make extracurricular activities in public schools.
It's my first year in high school too!
It's not that bad yet, but I heard that people from the third year of high school (here, high schools just have three years) stop doing everything because they have to spent all time they have studying, It seems like they have at least three books of each subject, At least, this is the reality in private schools.
