Is there any particular reason to do this other than:

1) to enroll in Duke TIP (they seem to have some nice programs, but it's not needed by us at this time);
2) to advocate (also not needed);
3) for bragging rights/to get recognition? (also not needed)

DD is a good standardized test taker, but she is not a math genius, nor is she likely to absolutely kill it on the reading section (her strongest language skills are in writing, which is not assessed). So is there any reason to do this?
