Sometimes, the reason why some people don’t get the grade they wanted in an exam is because of their inability to answer the exam questions. It doesn’t mean that they didn’t review and I’m not saying that they don’t know anything either. It’s just that their answers to the problems are getting out of the context. I mean that they write a hundred of thousand of words (even though it is not related to the topic) just to show the teachers/professors that they really know what they have been writing in their papers. And it’s really funny how in the end these people end up, angry. The instructions are clear, answer short and stick to the topic.
