90 - 我的逗逼考研经历 - just-a-story.txt

突然发现明天是研究生入学笔试日。在考研这件事上我有丰富的经验，包括失败的经验、成功的经验、以及出题的经验、面试的经验等等。我的读者分布主要在20-35岁之间，相信大多数人都有亲朋好友明天要上场，甚至自己要上场。把我的逗逼经历写给你们看一下，你们也转发一下，帮助缓解一下焦虑情绪也是好的。

第一次是大四，考的是本校本专业，按部就班复习都比较顺利。当时专业里大概三分之一人准备出国，三分之一人考研，还有三分之一人直接就业。考研的人里面只要认真复习的几乎都上了，好几个还在辅导班里顺便捡到了外校女朋友——颜值比我们学校的平均水平高很多。我总分还不错但倒霉在数学这门课成绩特别差，单科没有过线，比我正常水平要低20分以上，但当时没有查卷服务，只能作罢。

在要不要二战这件事上我稍微犹豫了一下，但很快决定要上。其实当时我已经拿了华为等几个公司的offer，参照同批去的同学现状，应该是错过了最简单的一次财务自由机会。
