Final Exam Time

Settle down, class! I know it’s hard to concentrate when the weather is getting nicer and you’re so close to graduating, but forget about senior slump—you still have to pass your exams before you can walk across that stage, so stay with me.

Victor, are you asleep back there? I know you’re tired, but you can’t sleep during a test. Jenny, please stop talking to Yulan and pay attention. I’m passing out the exam papers now. You’ll have one hour to finish. Remember, this test is worth 10 percent of your final grade, so take it seriously, please.
