假设你是 Jack，昨天你收到美国笔友 Mike 的一封电子邮件，邮件中，Mike向你倾诉他的烦恼并寻求帮助。请阅读邮件后回复。

Dear Jack,

How's everything going? I'm under too much pressure these days. The final exam is coming and I really want to get good grades, so I stayed up late to study for each subject during the last two weeks. I was so tired that I couldn't learn well in the daytime. Now I'm worried. Could you give me some advice? I would be very thankful if you could offer me a hand.

Yours,

Mike
