It happened to me too just the other way round because I joined the extra classes and the teacher gave us questions but didn't tell us that was what was coming for exams. But looking back I see the unfairness in what he did.
Because then again if I have no money to join the questions would have eluded me or if I was that good then again, the questions would have eluded me. But sadly, that is how the world is.
