Exactly: Why is homework considered something that can be "cheated" on anyway? The whole purpose is to get practice and learn the material.

Just make the tests challenging-the ones who actually did their homework will pass. The ones who didn't won't.

Wolfram Alpha helped me many times-sometimes you're simply stuck on a problem and no one is there to help. But like anything, you can use it to cheat and not do work, or you can use it to help you learn more.
