hi Real_not_perfect!
As someone who just graduated high school from the States, let me say that you don't need a 4.0 GPA to get into college! It is very possible to get into college! Many of them have certain criteria, like preferred SAT scores, preferred GPA, or foreign language requirements. You are allowed to miss a few of those as long as you have the rest.
as far getting through your classes now, talk to your school! try joining a club- at my high school, we could be a part of any club, but to really participate (like at concerts or in plays or occasionally field trips) we had to be doing well in our classes. maybe it would motivate you!
your parents I think mean well when they tell you these things, and you're right, there's plenty of time to turn things around! don't be afraid to ask for help. everybody around you has been through school!
don't be afraid to pm me if you need help! (algebra was one of my better subjects!)
