Agreed. I happen to use some open-source softwares equivalent to Adobe products. I’d do fine on a “vector graphics” test, but I don’t know the nuances of Illustrator that would let me pass it. They’re too stuck on rather useless details to evaluate if you actually understand the heart of the subject matter. E.g. on the Powerpoint test, one of the questions basically asked, “what icon denotes [xyz tool]?” I don’t know! I don’t think it was even a very useful feature, but if it were, I most likely wouldn’t recognize it well enough to pick out its description on a multiple choice test.
I think the tests are a good idea, but they’re just not looking for the right things.
