Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

It's not incorrect. It's just a proposal to create similar but a little more tricky kata. As far as I remember. And this example should give false result in this alternative quiz.
Excellent solution! Just:
char.IsLower(c) && char.IsLetter(c) can be replaced by char.IsLower only, isn't it?

Fine kata, but I also did't notice at first time that there must be the strict equality.
More strict definition of wordsquare ( row[i]==reversed(row[a-1-i]) and col[i]==reversed(col[a-1-i]) ) leads to a more interesting solution.
