Exactly. I told my kid i was not complaining but just would like to let the teacher aware there are different alternatives on answers. I said I would say it nicely. In fact, I was not aimed at chasing for the marks but just would like to let my kid know he's doing his paper correctly. But thinking of if I really do so but end up the whole class would be scolded...Where is my guts? I would definitely do so when I was still a student or 10+ years ago
