I noticed that about a year ago Khan had a few live SAT courses streamed on Youtube and was wondering why these were discontinued? I feel that these would be very helpful in teaching a variety of content while being able to answer questions. For some, the Khan SAT prep is overwhelming with so many categories to practice it would be nice to have someone just go through and teach multiple at once. I really hope you take up this suggestion because I love Khan and other live test prep services are just too expensive.
