DEAR JIMMY,
I have seen your problem from your letter. I know that it's easy to feel nervous before the examination and couldn't fall asleep well. I am writing to you for giving you some advice. First you have to take it easy and do some deep breath before you sleep, or drink a glass of hot milk before sleeping. These tips will help you get faster into sleep. Hope you can do a good job in your exam. I believe in you. Come on.
YOURS,
