My dear

How are you?

You know I'm crazy about the idea of studying abroad and experiencing other culture in different country even from my childhood, which will do me a great favor to expand my minds and widen my eyes.

Fortunately, now I have to a great opportunity to go to the United States for my further studying. However what troubles me is that mark of ToEFL test is needed for my plan of going abroad. Although I have been studying English very hard recently, I still recognize that it is not easy to get a handsome mark in this test. What is more, I find myself keeping on doubting about my memory because I just can not remember the new words, even if I have spent lots of time, which really makes me exhausted and full of depression.

So I need your help. If possible, I would be grateful that you could recommend me some helpful experience of learning English and methods to remember words. I will appreciate your great help.
