Some Senior 3 students can't study efficiently because of staying up late. What's more, many have anxiety, which also lead to the inefficiency of studying.
In the respect of the problem, l have some suggestion for them. First, they should have enough sleep, that is of great importance. Beside, striking a balance between study and relaxation is necessarily. Finally, it's a great idea to them to spend more time doing sports.
In my opinion, more attention should paid to Senior 3 students' health. I suggest they take care of them so that they can stay healthy and study good.
