Purchased a test after doing an Udemy test hoping for some added/supplimental material. They basically steal Udemy exams and use as there own. They don't "update" tests obviously because out of the 30 questions i initially took, at least 8 were incorrectly setup making answering correctly impossible. Contacted support to get a refund and they don't offer refund for "this type of thing". Double checked the "reviews" on there site and there is not way to ADD A REVIEW! Shaaaady.
I learned a lot from this experience, lots of bad test companies out there be careful.
