Checking a solution is often a lot easier than generating an original solution. If you are not going to be generating original solutions, I would guess that there are better uses of your time than learning how to.
In my schooling in general (at middle school and higher level), I was generally annoyed that most subjects were taught with the assumption that you were going to become a practitioner of that subject, rather than simply a user. Naturally, every teacher thinks their subject is the most important in the world (why else would they have chosen it?), but most of their students do not see it that way. I would have been far better off learning how to communicate effectively rather than psychoanalyzing literature, just as those bound for non-quantitative careers would have been better off learning the math they need to keep their finances in order than constructing geometric proofs.
