考试前：考试压力大→掉毛→秃→凉快
考试中：题做不出来→浑身发冷→凉快
考试后：考崩→战战兢兢→雪崩→凉快
考试真防暑降温之神技也。
还有一个礼拜就解脱了，夏天快来吧。

达尔文在棺材里高呼“专业”
We stand (1.5 metres) behind you! The evidence supports the theory: humans are social rather than solitary animals. We’re not made to be alone, especially not as students at the start of the examination period. But Darwin would be proud, as you’ve shown great adaptability. And that deserves our admiration and respect…but our sympathy, too, when things aren’t going so well. That’s why we want to help you with useful tips, informed advice, and as much support and encouragement as possible. Together, we’ll get through this – and through the examination period. Enjoy what you can, do what you need to do, and take care.

5欧的奶茶好贵，就当考完试给自己的奖励偶尔奢侈一下吧。

顺带发道题，凭本事拿人气，所有答对的大佬每人奖励3-10人气（截止6月20日22点）。

已知三黑今天下午考试的题库是20篇essay，考试从20题随机抽4题，然后4选2回答。但是20题中有一道题作为自选作业三黑已经做过了，考试时如果出现这道题只能3选2作答。那么三黑提前准备多少题可以保证在考试中有95%的概率碰到至少2道题是提前准备的？

最后完整准备了6篇，撒网准备了8篇，最后考到1篇完整准备的、1篇撒网准备的、2篇没有准备的。看起来90%的置信区间也可以接受，统计学诚不我欺
