Excellent question. My wife and I live in Irvine CA, and we have been aware of Calvary Chapel's school or worship. I looked into it in the past thinking it would really help us, but aside from the cost which is not trivial, it's a big time commitment, taking up all morning I think four days a week, for a semester. Given my work schedule, and also the difficulty for my wife always getting up and out the door early every day given health conditions and all... it just didn't seem that possible. I was therefore thrilled at finding this course online here, as it solves both the schedule and financial challenges. Thank you both for providing this great resource, it's a real blessing!
