详细分析统计，什么专业最难，什么专业最容易。加了原始数据截图
在CMU 校方统计各门课程实际每周学习的小时数，我把各个系科每个年级选取一门有代表的大课（皆为那个系科那个年级Unit最多的课之一），得到下面统计：

15-410 (OP SYS DESIGN & IMPL) = 25.0 hours/week
Total FCE = 76.7 hours / week
英文系的课程最轻松，而计算机系课程最繁重。
而且很多同学反映，
计算机课程挂科的最多，得高分的最少，很多同学的作业到期交不了，因为程序通不过。
而 文科课程，几乎没有不得A的，而且作业都能准时交。
理科（数理化生）处于两者之间。
另外，艺术娱乐系也挺累，很多作用和项目非常花时间。
不知道是否是 所有大学的普遍现象，还是 CMU 特有的现象
