A. You should discuss this problem with your parents. Have you talked to your father? Surely, he misses you, too. Tell him how you feel, and perhaps he would spend more time with you. You can also ask your mother to do something fun with you when your father isn't home.

B. You shouldn't worry so much. If you study hard, you'll do well. Try to relax, find time to go for walks and eat three healthy meals every day. Don't drink coffee or tea, or you won't be able to sleep. You'd better drink a glass of hot milk before going to bed.
