They encourage me all the time and support my daily expenses. Therefore，I can concentrate to improve my English on a full time basis, I locked myself in my bedroom to study and review English, meanwhile. I had attended an IELTS course on November 2003 in Guangzhou city．Through my effort，I had increased my IELTS score from 5.5 to 6.5 in half a year．Now I still insist studying English further more, I attend a spoken English course in Jiangmen City every week in brief, I want to say that I really want to study and I have enough learning abilities.
This time I am providing some new documents to support my qualification and my guarantors Capital. These papers include my parents’ certification of deposit, my new IELTS report，my English Test report of the University of Plymouth，the University English summer school course Offer of the University of Plymouth and the MSC degree Offer of the University of Plymouth etc.
