I checked out 3 other establishments in the valley before my son & I settled on SEC. Without even getting to know your kids' abilities, the other guys try to sell you their ACT or SAT packages.
SEC administered a test to see which test is better for your child. From there, they ascertain if a class makes sense. My son took a few private & semi privates & that's all he needed. I wound up only spending a fraction of the cost & we were extremely happy with the results.
