Isn't the last word in the test sentence ('with') redundant?

Better late than never, eh?

I wasn't a member back in 2004. However, earlier today a test-taker posted a question about a sentence in a test from this category. I clicked on one of the other tests just to see what else was floating around. Just a "lucky click", I suppose.
