My girlfriend will have an exam tomorrow. I want to write something to her. How should I write it?

Life has to go through many exams. At school, there are endless quizzes, weekly quizzes and monthly quizzes. When you step into the society, you have to go through all kinds of exams, such as written exams during interviews, exams for various positions, and professional exams. Every time you have an exam, you will feel nervous. Dear, I hope you can get encouragement when you read this passage, eliminate your nervousness and prepare well for the exam. I wish you the courage to work hard and sail to the ocean of knowledge. I wish you success in the exam!
