Appeal it.
My son wasn't recommended for honors level, or even advanced college prep level, math by his 8th grade Algebra teacher. My son had gone from enjoying math and doing very well at it to hating it- while continuing to do very well at it. It was a personality conflict with the teacher.
So when she didn't recommend him for honors, he was happy, he didn't like math anyway, and I didn't argue (yes this is on my list of "parenting boo boos I have made".) He went all through HS in the basic college prep level math classes, getting A's. He easily could have handled advanced college prep, honors, or AP. How do I know? Because he breezed to a 720 on his math SAT. Because he NEVER studies and always gets A's in math. Because he was doing advanced math at age 5. He just gets math, it's natural for him.
But he still hates it.
He's taking a pre-calc elective right now, but because of his SAT score he isn't required by the college he's attending in the fall to take math unless his major requires it. Which it won't.
So my son who was always so comfortable with math, and so talented in it, will probably never go beyond pre-calculus. Such a shame.
Appeal it.
