The word "listening" refers to the process of hearing and understanding the information heard. Besides this, listening can be classified as passive if the listener only receives the message without any response or really involved in the process of listening or as active if the listener fully concentrates on the words being said and can respond to them. In the case presented, in which your teacher is reviewing for a test active listening is required rather than passive listening, because in this case you need to fully involve in the process of listening to understand every detail as this information would be useful for the test and also through active listening you can respond to the words of the teacher by asking question if you have doubts. Therefore this situation calls for active listening.
