Short introductory videos are available from the course co-ordinators of several of the MSc courses on the department's degree programmes.
Please note not all courses will be running every year. Please check question 6 here for availability.
Not all available courses have a video, so be sure to consult the IR course guides for full details.
You can also watch all videos as a YouTube playlist or an iTunes U playlist or on LSE IR Department audio and video channel.
