Assemblies For Busy Teachers

Okay so my parents are totally unfair these days ..!
I got some bad grades and I am confused with things easily. And my parents blocked facebook (but I'm still on it on my phone), didn't let me go to school dance, and angry against me, like every day! And now, my mother says that until my grades improve it will take my phone! I'm so mad I could cry. Maybe that sounds selfish, but I really need my phone. It takes me a text! IM as a textaholic. and it is not unhealthy or anything! and I need to get on facebook other than the weekend. and I need to call my parents to the school if I have to stay after school. or when the school after visit, I watch a basketball game that I need to call my dad to pick me up. well you know, just to feel safe with your phone. It did not take away my phone yet. She just told me like 10 minutes ago. But if shes serious and she does. She said "shes very concerned about my grades, and my phone is probably distract me, and she must win for the third quarter, my grades get better." My parents think 7th grade is oh, so easy! It is not! I try really hard. Last night I stayed up two hours, like working on tests for English and now I'm on a good note, but my mother just said "good job" for that since it was too busy is excited about science. Okay so technically the only bad mark I have is science. In PE, I was one, in English, I was one, in mathematics, I have an A-in Spanish, I have a + in Global Studies I + b, but shes gonna cos bump my grade up a project that I recently turned in. It's just that science really sucks.
But thats not even just cos heres the whole story: We have this lady who is like a college science teacher assistant. so that the entire semester (today was the last day of the semester breaaak first winter-yay!), she was the one who taught us. Im dead serious. My professor has never even been in the room. It has always been out of the rooom make coffee, or on the computer by adding the grades and other things. She never paid attention to students. Thus, the last day this assistant professor was last Friday. And so Tuesday was the first day my teacher taught us scien regular. Cos on Monday we had a meeting, and today we had a assemly. Thus, since the beginning of the year, my regular science professor taught us for three days. So stupid cos if Tuesday night, she sent my mother an email saying that I did not do well in school. And my mother was angry against me. I was like WTF!? It was his U.S. education first DAY! What does she know?! And then on Wednesday she checked my notes on Edline (the site where teachers post cards from your report and grades) and they are quite low.So I was not allowed to go to the ball last night. And then today, she sent another email from my mother, saying "She was really concerned about me. I was not attention or get good grades in class." and stuff like that. I mean reaaallly??? She told me for three days of his life, and sends an e-mail from my mother every day to get me into trouble. oh.em.eff.gee! she hateeees. I am no more exxagerating. It's just stupid to send my mother emails you're concerned about my behavior if you havnt even seen my behavior. And even in three days, she taught us. It was just that she was the only teacher in the room. Yesterday, we made this online gaming website thing. and Wednesday we had a worksheet to do. So technically Tuesday was the only day she has never taught and paid attention to us EVER!
So anyway thats a lot of information to answer a simple question. But I just want you guys to know the whole story. So my mother is right? Vote yes or no. Justify your answer please.

Uh, I have time to answer yes or no difficulty in it. If I were you, I really feel like it was unfair. But your mother does not pass.
