Dear Tom,

I am so sorry hear you have some problems with your studies. But don`t worry ，boy. Let me help you. First, you must believe yourself and have a good sleep every day. Then, you must study hard and if you have some you don`t understand problems, you have to ask your teachers。And don`t stessed out when the exam comes。 The day before exam comes， listen some inspiring（励志的） songs， like Believe In Yourself （相信自己）。Finally， wish you successful！

Yours
