At my test center, before i even entered the actual test room. The person working at the test center handed me a laminated sheet of paper that had a list of rules, one of which stated that during our 15 minute break we were NOT allowed to look over our notes. If we were caught doing so, we'd be kicked out. That 15 min. break is strictly meant as a restroom break/snack break. Although I will admit, during that 15 minute break the person proctoring the test did not pay much attention to us.... Definitely not worth the risk though lol
