By Monday, I am meant to have a draft copy of my thesis introduction ready for discussion. The paradoxical thing about the task is that it will almost certainly be necessary to revamp the introduction a great deal, once the three core chapters have been finished. Of course, it is essential to get the direction right. Tidying up the introduction and conclusion is something that can be done during the period between when my supervisor leaves Oxford and when my thesis is due (April 1-22).
Hopefully, a generous soul or two will volunteer to read a few chapters (or even the whole thesis) to check for general comprehensibility and strength of argumentation.
PS. Lots more information, both about the thesis and other coursework, is appearing on the wiki.
