Second! Those nasty integrals in E&M became a breeze with WA. Our TAs learned to accept the application of a 'WolframAlpha' operator to solve them, since everyone knew they were just busy-work integrals once you got to upper-division classes.
Quite frankly if you have homework where WA can solve the integrals instead of you having to somehow "massage" them for it to even be able to "digest" it, your upper-division classes are not very upper at all.
