And try to make two separate threads next time please...however much the two things you talk about are related, they are very different.
Yes, go to the FIRST scholarships site. If you haven't done so, register on the
College Board website. They have amazing resources that not all students actually use when they should.
You must register for an account on there to use their resources though. Please use the site and also ask your guidance counselor about scholarships that you may be able to apply to. Also ask about financial aid - FAFSA is the common thing to fill out. Have you actually spoken with your guidance counselor about this yet? Good luck. (btw, there are other specific forums for this subject matter)
