At my school, we have interims, well anyway, like 4 weeks ago I got grounded because I had an F in bio, well I raised that to a B in a week.  and my parents wont unground me.  And to top it all off, I have a D in Geometry, only because I was absent the day before a test.  So like my teacher is going to let me retake that test, to raise my grade up, but report cards come out this weekend.  Well now my dad wants to double secret probational ground me.  Do you think thats fair???
Your parents just want you to understand the importance of getting a good education, which means staying in school, not skipping classes, paying attention in class, doing your homework, and studying for exams.  Once you prove to them that you take your education seriously, I am sure that they will "unground" you.  Work hard!
to stay above a 90 you need to score at least an 81 on your exam. \n\nthe equation that i used to get it was (93*.75)+.25x=90
