So, this is an extension of the previous poster's question, but more generalized. To have SOME reference for angles, do you think it would be suitable to ask the test supervisor to use the whiteboard pen or the edge of the laminated dry erase sheet as a reference line if promising not to touch screen? Is the screen rule widespread, does anyone know? I sure as hell hope so, because "guessing" angles willy nilly is pretty ridiculous; all angle ranking strategies rely on some reliable reference point (not a frazzled DAT brain).

Any help on this topic is appreciated; it will affect the way I study.
