| OK, here's the solution: In the first group, the answer can all be "A" with a number: A01, A02, A03, etc. The second group would be B01, B02, B03, etc. The zero is necessary since there are more than 9 answers. Then the solutions would be something like A01A07 rather than typing the whole thing out.
As to figuring out which ones you've already guessed, since the more you move along the more guessing may be required, I think that's a key part of the puzzle! |
