Academic knowledge includes the capacity to develop oneself as a learner. It is crucial to reflect on your own needs and goals and to evaluate your own learning. This also applies to the learning of foreign languages. When you can make a realistic assessment of your own level and needs, you can then also set your own learning objectives. This in turn means that it will be easier for a teacher to help you extend and diversify your learning.
