Could someone please send me the answers to Course F, Lesson 17, Puzzles 7-9. I'm stumped! It's the only puzzles I don't have completed (A-E finished). This is something I teach to roughly 900 students.
I am having the same issue - I got #7 but not 8 or 9 I'm guessing you never heard from anyone? All the blocks were there for #7, you just needed to add a codename (I used the word "hope") and put all the other blocks in order.
