It happened in Maryland in 2013.I agree with people that say everyone has to evaluate the "risk" for themselves. And there will always be a handful of overzealous proctors... but I literally brought in 10 from my college grad classes 100% filled with handwritten notes (plus an additional binder I created for studying). If a proctor honestly thought I wrote all of that during a 4hr exam... I guess they win and I'm retaking the test. It just seems incredibly improbable.
