Chad, I started–per your suggestion–on Freshman Video #2. I PICKED UP A TRICK I HADN’T CAUGHT BEFORE. JUST ONE SO FAR, BUT I WAS SO EXCITED, I WANTED TO TELL YOU RIGHT AWAY. It’s so simple, I’m amazed I didn’t catch it before. My worst fear in your videos to date is that I won’t have to enter each & every possible subset number in every cell. The complexity between Medium & Hard is so pronounced that neither my husband nor I thought there would be any other way. NOW I’M BEGINNING TO HOPE AGAIN. Thank you, thank you, thank you!
