Do you interrupt your study activities or do all the homework at one sitting?

I generally do my homework or study in one sitting. When I was a high school student, I studied for 13 hours a day. Not all Korean high schools make students study until night. However, my high school has a dormitory so we should follow strict schedules until night. This strict schedule was based on the study. I sometimes despaired because my high school has an excessive competitive structure. However, I had learned diligence and patience over three years. Since I graduated high school, I have tried to do my best even if it is a very trivial thing. Trying to do my best became my habit. In conclusion, I do my study or homework with concentration and passion in one sitting.
