L.A.
If your daughter is making A's and B's.. she will be fine. Just tell her to do her best.. If the teachers thought she would have any problems, they would have suggested tutoring..
Has she done fine on the test up to this point?.. If she has, no problems.. If she has failed any portion while in high school, have her ask her teachers for review sheets for those subjects..
Has she taken the PSAT or the SAT? How did she do on those?
I bet she will be surprised at how well she does on them.. Be sure to have her pick out some books to read after the tests.. the schools do not allow the kids to do anything but read once they complete the test.. even if they finish hours early. This was our daughters favorite part.. being able to read whatever she wanted during school for hours. We would go to the book store so she could purchase about 4 for the week..
