Thank you for your posting.
I was sorry to hear that you were disappointed about that. According to your writing, you’re a so brilliant student in your past, right? As a matter of fact I couldn’t say like you when I was young because I wasn’t a good student at all. But I believe, a first experience is challenging for anybody. Nobody can do well for your first time. That’s why shouldn’t beat you down. I think your mind is very complicated now. However this problem would be solved or not is dependent on you. You made a big effort in your life and so you got the scholarship. If you feel very hard about your work, people who around you feel it more hard definitely. But that’s only for now. Don’t worry too much. In near future, you will get used to do them.
You are still young. Please don’t give up.
I can assure you that everything will turn out fine.
