Mom deactivating Facebook (HELP!)?

[Katy]

Apparently, my mom thinks my grades are dropping (which they're not really), and she said if I don't get an A on my AP Stats and Honors Chem test I just took today, she will deactivate my facebook.

Here's some background info:
I've been raised as a stereotypical Asian student, I have a 4.24 GPA, and I'm the ONLY sophomore in my AP Stats class, and everyone else are seniors. At my school, AP Stats is a senior class, but my mom made me take it anyways.

The last AP Stats test I took, I got a B+ (better than almost everyone), but apparently it's not good enough for my mom. I don't know how I'm supposed to get an A! It's pretty much impossible! I study hard, or at least I try to, and when my mom told me, I said that I try my best and that I study hard, and she was like "STUDY HARD MY ASS"...

Soooo what should I do? Telling her I try my best obviously won't work, and I know she WILL deactivate my facebook if I don't get an A. I need my facebook account, for many reasons. One, all my friends have it, and it's how I stay in contact with many of them. Two, my sophomore class has a group on there where we discuss announcements, spirit week, etc. Three, when my friends have birthday parties, they invite me through FB, NO ONE CALLS EACH OTHER. In fact, most of us don't have each other's numbers, and four, if the teacher forgets to announce what the homework is for our class but says it in another period, my friend from that period tells me over FB so I know what to do.

And it's not like I have no life aside from Facebook either. I hang out with friends even though I'm stuck at home doing work most of the time... and I don't even spend that much time on Facebook!

How do I convince her? I told her I tried my best, I told her I'll improve next time, I told her I need a social life, but she won't go for any of it. I told her that I don't even spend much time on FB and she was like "Good, then deactivating it won't be much of a change." She's just like the tiger mom. Help?

Serious answers only please!

Thanks so much in advance!

Respect your parents and do better. Facebook is for attention whores with no life except for that they have online. Stop acting like your world is ending over a stupid facebook page and grow up, brat.

wow ignore that hello guy. i think you should tell her the stuff you just typed out in this message and try to get her to see your point of view. hopefully you got A's on those tests so you won't have to deal with all that.

why do Asians worship money?
there is more to life than money ,there is a thing called happiness and money does not make you happy it just gives you a different level of misery
