HIE, that is reiterating the rule, in other words, not only will the cell phone be confiscated but you will also get a ZERO on the test. It is not allowed period. If you bring it to school put it in your locker, you are not allowed to walk around the school premises with your phone. It doesn’t make a difference which rule you are breaking, if you agreed to the rules when you entered the school then follow the rules.
