Still need time to improve

Yesterday (June 23.2011) was the time for level 3 of medical students to take their TOEFL test results. From 32 participants, there was only one who got the target more than 450 scores. One of them came to us (as the lecturers) and asked us,"Can we take another test outside?"  We have already known what she meant. It meant that she wanted to buy another certificate without taking test so hard again. Why should she or other students take that way while they still have time to take and study again. They need to reach the target for their graduation but they will graduate next year. They still have time. But why don't they think about study to reach the goal so they will get more, not only get better scores but they will get some knowledge. Okh, come on!
