life, liberty and the pursuit of geekiness

I assumed that as Martha talks about being a medical student, she is therefore is at one of the London hospital medical schools doing her clinical training, and thus a student in her 3 - 5th year (4 - 6th with intercalated BSc, which I think is compulsary there), rapidly forgetting everything she knows and is going to require the Doctor to faciliate three months on an island with her books before she returns. She's certainly not at the JHO/whatever it's called stage.
