Just before now, I had told with ex co-worker in the company to which I belonged previously.
He said that OA6.5 of IELTS is regarded as a enough score to fuifill a condition to study abroad from a comment of his colleague(a professor).
So I regret that I could get only 6.0. If I had had a better score, I will show my score with a condident attitude.
I will take IELTS soon and expect to get over 6.5. I believe that I will overcome the hardle because I was given much energy in the party with MBA applicants.
