G.P.A and reassurance questions from the out-of-the-norm high school student?

Hey there...sound like you have a great spirit and your heart is in the right place. You sound a little lost haha but aren't we all? Anyways, I think as far as calculating the weighted GPA, you can ask your counselor about that? Also...all your extra-curriculars will for sure get you into a great college. If anything...you can always go to a college that accepts you (even it is not your dream college) and then transfer to another one if you feel you're not getting the education you want. College is in no way set in stone...and after you graduate...it honestly doesn't make a world of a difference where you have graduated from. Employers are always looking for experience over the name of your college....at least in my experience. So basically, apply to a bunch of places...don't rush into declaring a major...and continue living your life with the same curiosity and enthusiasm that i see from this post.
