I think we should drink milk. Milk itself is nutritious and good for your health. You can drink coffee occasionally, just to refresh yourself, but don't drink too much, it's easy to get addicted, and it doesn't feel good to drink too much. It's better to drink pure milk.

During the postgraduate entrance examination, you can prepare some nutrients with milk. After all, the postgraduate entrance examination is still a protracted war, and the process is hard. Take good care of yourself so that you can study! ! ! !
