You return to the theme itself in an advanced course in your third and final year. There you will be reunited with students who may have followed very different paths through the programme to your own, to debate the problems and research issues together with guest speakers.
You may choose courses from different disciplines which will count towards your major requirements as many courses are 'cross-listed.' This means, for example, that the course in question is valid for a science or a social science major.
You will be able to use the knowledge you have acquired in your major during your second and third years to make an informed contribution to the debate, while the different paths that you and your fellow students have followed will allow you to bring a variety of insights to the discussion - the course will help you to integrate these insights.
