School districts are warning parents and students about a tough new rule for students taking the Regents exam this year.

There's a new "No Electronics" rule. Cell phones, iPods and other electronics are not allowed to be brought into a testing room. If a student is caught with an electronic device during the exam or even a bathroom break, the exam will be invalidated.

The "No Electronics" rule will also be in effect for mid-term exams taking place this week.
