Do you deserve a phone
Do you really want a phone, and want to show your parent that you are responsible for a phone. Then this is the perfect test for you. After this test if you get a low score try to get good grades and try to persuade your parents your self.
This should be the test for you because, if you want a phone and know that your parents will say no, you could just take the test and maybe prove them wrong. I hope after this you get a high score and get that phone!
