It sounds like everyone is having an exceptionally busy week, with school starting, work, music, sports, and other activities....
My schedule is filling fast too--with good students who want to get a jump on studying for the more challenging subjects. As you know, when we can study together consistently, it will make a much bigger difference than just a lesson here or there.
You deserve the best education, so why not give yourself the best tutoring? Like they say, a good education really pays -- FOR LIFE!
