What're the options? But also, more generally, choose what interests you and if you don't know what interests you, research the options to understand what they do and then choose. (Though I'd have thought if you managed to get a vac scheme, at some point they would have asked you what type of work you're interested in and why them)how do I choose a department for my vac scheme? I have no experience in either of themwhich ones tend to be the hardest departments for vac schemers generally
Also, departments don't tend to be "harder" for vac schemers because vac schemers for the most part can contribute very little outside of standard stuff like proof reading for grammar, which will be the same across all departments. Go with what interests you.
