A student is someone who comes to a palce of learning to seek and acquire knowlegde. A professor is a learnt person of knwolegde who makes that process possible and happen. In this learning and knowlegde transaction, the learner by default should not be accountable for not knowing what he is learning, but retaining and knwing for what he has been taught and learnt. This process does not allow other behaviors to surface, such as mentioned in the comment " student humuliation".
