differences in education between my country and USA

At the end of last Friday, I had been Seattle for one month. This is a period of time which is not long, but not short. I had many experience, good and bad in Seattle. I don’t know how my English was improved , but I hoped. I had more new friends who are not only VietNamese but also different countries with different cultures such as China, Japan, Korea, Kuwait etc. However, they have same thing which is they are friendly and kind. It is very exciting. I have perfect opportunity to know more about many countries.
After 3 week studying, I realize some big difference in education between my country and USA. Firstly, my instructors are ver friendly, they look likes more my friends than my teachers. In Viet Nam, although teachers are kind, but it exists a distance between student and teacher. They need have respect behaviour with their teacher, for example bowing when they meet their teacher. Secondly, each class owns a private classroom. They don’t need move and wait teacher for next class. In Seattle, both students and teachers have to change classroom between 2 subjects. Next, in highschools and lower levels, students have to wear uniforms and follow strict rules for example dye hair or a boy is not allowed to have a long hair. They study in text books and don’t need find out more information on Internet or TV. However, they need many reference books because program is hard. Almost of them must to take extra class after school. They study for some important subject such as math, chemistry, physics, biology, literature and especially english in a centre or at home of teachers who may be their teacher in school or a good teacher in a famous school. The reason is they afraid of studying worse than their classmates and it’s not easy to take a place in university in my country. Every year, new students are 20% quantity of candidates. They need study at least 2 or 3 hours per day in a centre or with a teacher after school. In Seattle, there is a break during 2weeks between 2 quarters. In contrast, students have to study during 9 months continously and have a summer vacation. In Seattle, I have quiz, test everyweek. In Viet Nam, I also had many quiz and test but not everyweek and some of them are no predict. In university, students have one exam per class at the end of semester. How do you think about studying in my country?
