Jessica: You're not alone, Yiru! A lot of college students pull all-nighters for exams. You can also use the phrase "cram session." It means an intense period of study before a critical exam.

YR: C-r-a-m, cram, 是仓促备考的意思，所以 a cram session 就是考前的突击复习。正说呢，My study group will have a cram session this afternoon for tomorrow's exam. Hopefully we can get everything done before midnight so that I don't have to pull an all-nighter again!

Jessica: Take it easy, Yiru. Isn't your exam tomorrow an open-book test?

YR: Open-book test? 哦，你是说开卷考试吧？没错，这门是开卷，可老师对开卷考试的答案要求更高。我可不想考砸了！

Jessica: You won't bomb it. You're a smart girl!

YR: 你说“bomb"--那不是轰炸的意思么？我猜这就是说没考好，对么？

Jessica: Exactly.

YR: 那要是不及格，挂科了，怎么说呢？

Jessica: Then you can use the verb "flunk", f-l-u-n-k, flunk. It means you fail to pass an exam.

YR: I don't want to flunk my exam, so---I gotta go!

Jessica: Before you go, tell me what you've learned today!

YR: 第一，开夜车，通宵学习工作，叫 pull an all-nighter; 考试前的突击复习叫 cram session;

第二，开卷考试是 open-book test;

第三，考试考砸了用动词 bomb, 不及格则用 flunk！
