I liked high school here in the states. Well let me put it differently. I liked the classes and the homework. The people not so much. It was a good experience until I got to college and found out that I was not at all prepared. I struggled and that coupled with my MI issues caused me to freak out and drop out. I want to go back to school some day.
Ten hours a day is a insane. And that is for the lucky ones! Holy Cow! I wouldn't like that either. It seems like you don't have any other option. I don't know if Taiwan has a GED program but if they do I would suggest doing that instead.
I understand that Taiwan has one of the toughest school systems in the world and I really feel for you. You can do it and then you can go to University where you please or you could do it and then go where ever you please anyway.
