My parents are very strict . They don't let me party all night , no Facebook [ although I have a account without there knowledge ] . Once they found my boyfriend's pic on my photo . And so they are now admitting me to a new school , because of my boyfriend and my declining grades . What should I do to convince them ?

If you are sneaking around and your grades have dropped, what makes you think they would change their minds about sending you to a different school? Maybe it's time to get with their program?

May we know how old are you? Let alone boyfriend and Facebook, your falling grades are reason enough for them to switch you to a new school. And why exactly should they allow you to party all night?

My answer can be different if you are 12 or 14 or if you are 20.

They don't let you party all night? OMG! That's terrible!

In all seriousness you live under their roof, you live by their laws.

Maybe if you try befriending your parents more and become buddies and just do what you're told and start concentrating in school they'll see that you're determined to stay in the school and because of the commintment you've chosen to make there will be no reason for them to make you change schools . It's up to you not up to your parents .
