I want to ask you, what is this for? According to the case, the mental state is the best when you run in the morning, do morning exercises and have dinner. Why do you sleep in class? Listen to more lectures, study more, and your exercise method is feasible ~ but I suggest that 6 o'clock is a little early, so push it back. Students usually go to bed late at night and get up at 6 o'clock for two reasons: First, your sleep time and quality will decline. Second, it's getting colder and colder later, and you won't last long.
