When you are preparing for the optimal study session, you should remember to put your phone out of sight, preferably in another room.
turn the ringer off your phone and put it on vibrate.
turn the television off or on a program that doesn't interest you.
All of the above.
None of the above.

to me i think class room sitting education is better. i do online school and i have not learned a think haha. when i sit in the classroom i just sit there and kind of pay attention but still i get so far ahead in the class when im doing online i have nothing else better to do but play video games and i sit in school and learn and have friends and just actually learn. when i'm doing online i sit here listing to music and get on and and look up the answers i guess that is my fault for being a cheater. but to be honest i think sitting in the classroom is better.

what are you asking? this is gibberish.

a is the indefinite article
