Dear Nick,

Thanks for your reply. I was very glad to receive your letter. I miss you so much and I think about the time that we spent at the camp. It seems to me that it was the best summer ever. But time moves on and I’m getting ready for final exams at University.

This year I have to pass the test in English, History, Literature, and Psychology. History and English are compulsory exams, while Literature and Psychology are subjects that I have chosen. It is a difficult time for me because I brush up on information for these exams day after day. I’m really anxious about them. Hopefully, I will get good marks.
