LOL! Sorry - that's what I get for assuming I've looked at something before! The PDF comes up with the hardest problems first. That said, what I lack on the harder ones isn't computational power; it's "how do I start this." But yes, I think enough of those are accessible to her that it's worth giving them to her with plenty of encouragement.
