<p>There seems to be confusion on the meaning of “test bank.” The thread violadad mentioned seems to talk about test banks written by textbook publishers that are a collection of questions given to professors to use to create tests and stuff; I don’t think you can even obtain them unless you are a professor, and are definitely not allowed to be used.</p>
<p>The test bank that tiff90 is talking about is just a collection of notes, homeworks and tests from a class that someone took, though I’ve only heard of them being referred to as “course bibles.” I think these are more accepted, though I’ve had a few classes that explicitly stated that they weren’t allowed to be used.</p>
