I've visited those places and they are pretty much the same. Whether or not they are right for your daughter depends on her. My brother went to Sylvan for math when he was in middle school and it helped him. However, I took my son to Score and was NOT impressed at ALL! I have several friends who are private tutors and they too say that the various centers are not that great.
You might look into Creative Tutors, Special Effects Learning Links, and flip to the back of the Dallas Child Magazine for other private tutoring agencies.
Good luck!
