Our CS major's main weeder class had two unusual examinations. The first one was to recreate a small project that you'd done recently as an assignment within a few hours, on-site in a computer lab. It could be one of three possibilities, which makes raw memorization a bit harder (though not impossible). The second was after the first big project, a project that's usually a few thousand lines of code; relatively large by the standards of a student. This exam was a bug fixing exam: the TA's randomly insert three bugs into your project's source, and you have to find and fix them within a few hours. Not terribly challenging if you really did the project by yourself, but if you cheated I imagine you'd have a hell of a time.
