Dear Tony, 

I hope this letter finds you well. I hope this letter finds you well. I heard that you are feeling stressed about your upcoming exams, and I want you to know that it's completely normal to feel this way. To help manage your stress, try creating a study schedule to organise your time better. Remember to take regular breaks to relax your mind, and don’t forget to practise deep breathing exercises. It can really help you stay calm. You've worked hard, and I know you can handle this challenge. Good luck!

Best wishes,
