9 English Idioms and Expressions in Context: Ace, Cram, Flunk, Killer, Pull an All-Nighter, Slack Off

Situation: Two friends are talking about their English classes and studying for tests.

Su Rin: How is your English class this semester?

Min Hee: Great! We talk a lot in English. I think I’m going to ace the final exam.

Su Rin: Really? My class is killer. The professor never stops talking, and we have pop quizzes every class. I’m so tired of pulling all-nighters. I’m afraid I’m going to flunk.

Min Hee: Hang in there. Don’t slack off now. The end is in sight!

Su Rin: True. One more night of cramming, and then I take my final test. I just hope I don’t oversleep. Our professor won’t let us make up the final if we miss it.

Min Hee: Yeah, oversleeping and missing a test can really hurt your grade on the curve. Don’t stay up too late. Getting enough sleep is just as important as studying.
