<p>As a comment on engineering - I know several chemical engineers and they have a very challenging course schedule. But they also get to do some of the most high tech research on campus once they get through their introductory courses, so there is a tradeoff. Engineers don’t spend all of their lives in the library, but they do study a lot more than many AS students. No science major is easy, but some do require more effort than others. And yes - you technically are trained to go to work right away after college.</p>
