So basically i get al lot of hwk but i cant do it and then i get detentions how can i stop this from happening

Talk to your teacher about the homework. 
And maybe it seems like a lot because it's hard for you to do. You should try to learn the material better, then you'll be able to finish the work faster, and it won't seem like much. 

Hope that helps. 

No must be 16 or 17 then you have to have a parent or guardian to take you out or   a court give written consent to their withdrawal. smh why would you be pregnant at
