Toeic test

I had a Toeic test this morning. The test was hold just at our school. Today I was unreflective. First of all,I used my ID in order to check which examination room should I take the test. But I mistook the numer. I went to the wrong examination room. Besides, it was just about time that the test is going to be start.I was very nervous. Finally,the service personnel of toeic help me to find out my examination room so I can entered the room on time. I felt so embarrassed because I was the last one when entered the examination room. I will make sure everything before I take test next time.I would never allowed that rediculous thing happened again.
