I've also taken a bunch of these "certifications". They are kind of easy but it seems like a good idea to gauge your skill for a particular app. They haven't gotten me anything either and I'm not sure I'd put them on a resume but if you have nothing better to do and don't have access to regular certs then it's a decent resource. At least until they start charging for it.
