I did several of them this way as well. At first I wasn't even reading the description to the right and just typing in selectors based on the instructions. So if I knew two comma separated selectors would work then that's what I typed in. Without going back over it to check, it's possible I entered selectors on a good number of them totally different than what was expected. It would be interesting if the answers were tracked so we could eventually see what different developers were entering as selectors on each one.
