Dear Jack， 　　Thank you for your congratulation. You asked me to offer some advice with regard to preparation for the postgraduate entrance exam. Now, I want to give several suggestions. 　　First of all, nothing would be more important to plan your ideal college and your review schedule in advance. Second, keeping a good shape by regular exercise is a sure-fire way to make your study more efficient. Last but not least, you are suggested to never give up even if sometimes you would feel extremely tired and depressed. 　　I guess I will quit writing now. I hope you will find these suggestions helpful. I am looking forward to your reply.
