As he bowed his head to delve into the answers, time quietly slipped away. After checking his paper several times, he looked at the clock, only a half hour had passed. He rubbed his hands. Since starting school, he had never finished answering questions this quickly. In past exams, he would scratch his head and cast anxious glances all around until the test was over.
This time, he finished so smoothly. There were only a few blanks left, and he regretted once he saw the questions he couldn't answer. He had definitely seen these before, but he completely forgot about them. He would have to watch out for these little problems in the future. Otherwise, like today, he would skip several blanks, which could cost him at least five points.
Uneasy, he carefully checked his paper several times again. When he found no mistakes, he waited to hand in his paper. Until the bell rang, this exam was over. After a ten minute break, it would be time for the math test.
