There is an examination which contains multiple choice test questions.
These test questions aren't published anywhere (only the official test company has access to them). We have a licence from this official company to publish their practice questions, but only the ones they give us.
The official authority also has the official website with the same questions (but they don't include the ones in the official exam).
Basically the official questions and the practice questions are 2 different sets. I can see that since the practice ones are published on their website, we need a licence from them (which we do have). But what about the exam questions that aren't published? Can we add them to our website and say that "we came up with them ourselves?" Also, what if we advertise them as real test questions?
