As for how often to go home, it depends on the specific measures of the school. Sometimes there are two days off every two weeks, and sometimes there are two classes in the morning and afternoon every Saturday and a day and a half off (either one will last for a long time, at least more than half a semester)
You must take it with you. Let's talk about it from the school again. There are pillows, pillow towels, sheets, washbasins, toothbrush cups, mosquito nets and kettles. So you also need soap, towels, toothbrushes, and a small quilt when it is cold. Others want to take it away or buy it again.
The point of attention is not to take the wrong class, which is embarrassing and funny.
You don't have to take the exam, you will be divided into classes on average according to the results of the senior high school entrance examination. Military training is available, not scary.
