I'm not sure if some of the people in the thread know how horrible having to stay in a house where you've been told you're not wanted really is. I'm not going all 'Oh you don't know *sob*' on anyone at all - I know tons of people have been in this situation and made it through, and I would advocate staying as long as it's possible. But it might be that the OP needs a couple of days or a week out of the house to let things cool down, or it could really be that moving out would be the best option. What if having to live in that environment is having a negative effect on their studies? What if, staying with a grandparent or something, they could salvage their relationship with their parents and get the grades they deserve, as opposed to staying at home and being unable to study because they're unwanted - ruining the relationship with their parents and doing badly in their exams?
I'm not saying that moving out is without doubt the best plan for the OP, I'm just saying that the people saying 'stay at home until they physically force you to leave' might not be in the right.
