In spite of studying abroad, you still need to improve English a lot. How did you study there?

Question: In spite of studying abroad, you still need to improve English a lot. How did you study there?

My answer :

I have never been (in) to a foreign country to learn English before.
I know well I need to improve my English and I am short at precise selection of vocabulary.
To get better in English, I'm trying to use English in various ways such as lettering with a foreign friend,
doing a preparation for English interview, getting a feedback (to) on my essay from native English speakers.
I will (excel) improve my English skills (within fastest time) as fast as possible . In addition, If I have (a) the chance to go to an English-speaking country, I will go to London which is well known for Project Management Course to study PRINCE (PRojects IN Controlled Environments). 

* I attached my records. I don't know how to tell intonation and accents.
I need your help and give me some tips for my records, please.

you're really good...I hope I've been helpful to return the favor, 'cause you really helped me out a lot till now, I’m not a native speaker though, so please wait for someone else to correct it too. ^_^

 ( I wish I could write something like that in Korean.. :)
