Ignore my comment in the other thread about not having the test graded, unless you just faint and do not complete.
Have the test graded. If you get a 1 or 2 for real, you could opt to take CalcAB at school and retest next year, giving you CalcAB as a sophmore at a 4 or 5, which is impressive. Junior year you could either take CalcBC or consider taking Calc3 at a community college or whatever your school offers. If you get a 3,4,5 you could opt to take Calc BC next year, at school. The CalcBC test retakes CalcAB first section and rescores, so you could potential get say a 4 or 5 on BC and have your 3 in AB replaced by a 4 or 5. I would recommend with a 3, that you would really discuss taking CalcBC with the teacher and maybe take the CalcAB final to show readiness for the course (or midterm at least).
Are your parents trying to get you into MIT or CalTech ? Did they follow this wildly accelerated program themselves ? Does your school understand what you (or your parents) are trying to do ?
Short of regional top 20 high school in America type magnet schools, you are wildly, I mean wildly, ahead of your peers.
Don’t sell yourself short, if you were able to do the problem sets and follow your tutor, you are exceptional at this age. Please see yourself as a very, very bright young lady.
