    What? you want to know the reasons why students are not allowed to bring gadgets?

    1. the teacher will confiscate your cellphone and will bring it back jn the end of the school year.

    2. if your having a test, and your using a phone, the teacher will think that your cheating or the teacher will think that your busy at your cellphone and your test will be blank.

    3. if you bring a phone and somebody calls at your phone an your having a lesson and if the phone rings, everyone in the room eill concentrate at the noise that your phone is making. and your teacher will probably take your phone and send you a page slip.

    4. if you are using your phone in the class while taking a lesson. an if the teacher asks you what is the lesson about and you don't know the lesson! for sure youre cellphone will be confiscated plus your patent's will be called by the teacher or even by the principal plus you will be grounded for the use of cellphone by your parents and maybe your phone can confiscate by your parents or may not bring your cellphone back!
