I'm a native English speaker, so I certainly couldn't care less about some IELTS test (whatever THAT stands for). But, one of the questions seemed unfair to me.

I can't cut and paste the passage because it always puts me over the character limit if I do, but it was that question about the new treatment being so effective that a large majority of the patients reported a positive response to it. Then the trick question was ALL the patients were happy about the new medicine, which was obviously wrong because all doesn't mean "large majority" , ("large majority" is like what, 80-90% or something?) but where did the writers of this test get the idea that a "positive response" to a medicine equated with "happiness" with it in patients? That's a dumb statement.  A positive response means to me the medicine was effective, not that people liked it. What was that supposed to mean? What kind of medicine was it, some feel good medicine or something? It was a weird and misleading question in my opinion.
