In any case, there are many things to pay attention to in American college life, especially finding a suitable balance between study, work, exercise, diet, sleep and leisure.
I don't know whether you study in the morning or at night. The most efficient reading time must be reserved for class. These can be regarded as a fixed time of the week, such as 1 8-1reading on March 3rd and 9-1reading on February 4th. It is best to have a rest time of 10 minutes between hours, because continuous learning is easy to fatigue, and the best time is about 2 hours, after which the efficiency begins to decline.
In addition to fixed class hours, sleeping and eating are best fixed, because fixed eating and sleeping will make your body regular, so it is not easy to get sleepy or hungry when studying or doing other things, so as to avoid wasting time.
Naturally, I won't say much about working hours. Unless there is something very important, the general work must be completed on time and with good quality.
Exercise about 3 times a week for more than 2 hours each time. If you want to lose weight, you can increase the number of times you go to the gym. But the maximum duration is 2 hours, because after 2 hours, it is overloaded, and it is easy to cause muscle aches the next day. Remember to warm up for 10 minutes at the beginning, and relax for 10 minutes at the end, otherwise it is easy to strain.
Other things can be put aside, including writing papers, entertainment, parties or going to church.
I hope the answer will help you. Thank you.
