Studying Chinese students spend the most time studying. Almost half of Chinese students spend more than two hours on their homework every day. That’s much more than students of the US (26.4%), Japan (8.2%) and South Korea (5.2%). Sleeping in class Japanese students fall asleep in class most often. About 45% of them said they sometimes doze off (打瞌睡) in class. In South Korea, it’s 32%; in the US, 21%; and 5% in China. Taking notes South Korean students don’t like taking notes. About 70% said they write down what the teacher says in class, many fewer than in Japan (93%), China (90%) and the US (89%).

Doing after school In their free time, most Chinese students study or surf the Internet. Most American students hang out with their friends. Most Japanese students do physical exercises.
