Triple Challenge is a wonderful Test Prep center for TACHS, SHSAT, and tutoring. Send my son a couple of years ago before taking TACHS & SHSAT tests.

I have referred many families to this center and will be signing up my younger son for the classes next summer.
Pros: Small class size
Cons: none that I found
