I am really enjoying your videos, progressing nicely. I’m not rushing them, still on Sophomore but WOW they have changed my whole way of tackling a puzzle. Not to say I don’t make any mistakes, sometimes i have to erase a couple of blocks and start again but i make sure i finish them without peeking at the answers or just giving up the way i used to. Thank you again for your concern, you are a great teacher!! If I may call you that.
