As students, we have classes from early morning till late afternoon. Therefore, take a ten-minute break between class is definitely important, even necessary. Otherwise we may feel both physically or mentally tired. During the ten-minute break we did something to get rid of tiredness. What we need is to have real rest instead of getting even tired. So don’t do anything what will make you too much excited. My ten-minute break is always pleasing. I usually do some simple exercises. Sometime I have a free chat with my classmates or just take a walk during the break. When the new class begins, I feel freshly again.
