The original post was at Res Gerendae (http://resgerendae.wordpress.com/2012/04/12/advert/) and there are a lot of other videos for different subjects over at the Cambridge YouTube channel. We mentioned in our post that we would be happy to answer any queries that applicants might have – they can get in touch with us via the blog. 🙂
