I suggest taking some daily necessities: such as toothbrushes, towels, clothes, etc. It's best to bring some money (never too much) and a notebook and pen with you, so it's better to remember at any time. Freshman training is very tiring and I fall asleep every day. Therefore, in addition to daily necessities, there is no need to worry about bringing books and toys to relieve boredom, which is basically unnecessary.
