Dude I am not gonna answer this…I mean like I dont wanna make it so u get in trouble with the HONOR CODE or anything…OH YAH u agreed to an HONOR CODE when u started Connections ACADEMY…Maybe you should go bavk through and read it again…Well that is if u are able to read…I am not gonna read it to you. Please stop this nonsense and study by yourself…Oh and why are you so far ahead…U still have time to study if your this far ahead. I am a ninth grader also at connections academy. Dude so please take 2 hours out of your day and brush up on the skills needed to pass. What is gonna happen next year when u take the high school exams. You are not gonna be able to pass because you are taking a short cut now. Travel Down The Road Less Traveled and study your heart out. Please dude do it for your future. and sorry if I sounded rude because it kinda does. But I just don twanna see another dropout because you cant take 3 hours out of your day…Have a nice rest of te year…Only 6 weeks LEFT WOOOOOOOOT!!!
Brandon (who sounds hot) is right. We wrote our name out onto that piece of legal paper and now you have to abide by it… sorry but it’s true.
So! I have one thing to say… “You better work!”
Watch RuPaul’s Drag Race on LOGO Mondays at 9 it’s not exactly study friendly but I’m hooked!
HAHA rock on Brandon…that was straight forward too…but seriously i love math…i mean it could be hard doing it online(thats why im goin back to regular school)But still its more challenging and gets your brain working. I mean Connections Academy has tutoring…if you need help instead of getting answers why dont you go and get a tutor? TAking a couple hours out of our day isnt gonna hurt you, unless you have an issue of keeping still and or just dont want to learn. Take it from me dude i cheated once and i learned my lesson….it was freakin scary! But you learn from it….for you dude i hope you learn before it happens to you and you end up gettin it on your record. And i know right brandon ……Omg i cant wait still school is out, 6 MORE WEEKS YESS and we are all FREE lol
