Right, but if you have questions during the video, you have no one to ask unless your tutor is watching the videos with you. That would be cost prohibitive here, I think, where private tutoring runs around $75/hour for middle school math! I'd guess it's even higher at the high school level. Still cheaper than private school though, I suppose. (I scored perfect on my SAT's (and the SAT II's) too, but I don't think that alone qualifies me to teach high school math! The SAT is capped at a 9th grade level, I think.) Don't get me wrong, there are a lot of issues with public school. If I had a motivated kid one on one, I could teach them a year's worth of math material in 4-5 months instead of 9, thanks to the yahoos in the classroom who slow things down. I still think it's a better model for the vast majority of math learners though, unless the parent (or other teacher) is well-versed and competent in math/physics/chem/etc.
