> A variety of coding and SAT “prep” websites discuss ways to bypass Bluebook security. One way is to use a plug-in that seems like a mouse, but is, in fact, a video capture device. Another is a program called a “sandbox, an isolated virtual environment that can work without detection within a computer.

I assume that "plug-in" means peripheral? Seems very difficult to catch all of these people, since a proctor won't be able to inspect the device and tell whether it is a regular mouse or something trickier.

Virtual machines seem like a game of cat and mouse, and one which the SAT is likely to lose.
