This isn't the normal place to make corrections, because it's not a notebook entry, but I know that I can make corrections for you, which I enjoy doing. O.K.? 

I'm interested in America. I wish I can could study there.

I'm a shy person, so I don't think I can do well in my toefl exam.
Sometimes I think I'm just no good in English, so I need someone here to talk to, with someone who can help me with my conversation skills.

BTW, think positive. You can do it!!!

If you mention TOEFL " IBT ", it is so difficult and has many tricky questions. There are few requirements to be qualified for the TOEFL test such as: Firstly, read, listen more and more. Secondly, study the grammar, structure and the essential basics of English. finally, search for some one to correct your pronunciation and writing essays .

Good luck
