TOEIC!!

I had a TOEIC test in my school. I had ever had the TOEIC test only one time, therfore it was second test for me. The score of first test was not so bad. I wanted to up my score but I didn't have enough study. At the begining of the test I concentrate in the test but the concentration did not keep until the end of the test. Sometime I was a little sleepy. Maybe the score of this Toeic test is not good. I regreted that I didn't have enough study for this test and I could not keep my concentration. I want to do my best for next TOEIC test!
