Some will tell you lots and others will tell you some. It is honestly more about strengths and interests. For me, paper writing and reading is a strength. For others, they would rather do differential equations than reading a chapter. My best friend was a math major and the thought of writing another essay would make him bang his head against the wall. The work load is heavier as an engineer. I know plenty of engineers who got plenty of sleep and managed their time. I also know some poly sci majors who did not. It really comes down to what interests someone, goals and their strengths.
