Hello, Peter. I’m very grateful for your concern about my coming exam. To tell you truth. I have been busy prepare for the exam recently. Some classmates are facing real stressed due to the exam, but I don’t take them so seriously. I always learn in a relaxing mood and I’m making a great progress. Now that I had tried my best, it doesn’t matter much to me what the result is.
In my opinion, we should keep a good balance among our study, rest or exercise. I believe we can be succeeded if we prepare for the exam in a proper way.
I’d appreciate it if you could give me some good advices.
