I'm about to go into my final(3rd) year of a maths BSc in the UK at Warwick university, and am currently looking at what options I'd like to take given that I'm hoping to go down the path into theoretical physics academia. I currently hold offers for Imperial College's "Quantum Fields and Fundamental Forces" MSc, Durham's "Particles, Strings and Cosmology" MSc, KCL's "Theoretical Physics" MSc, and Sussex's "Particle Physics" MSc, with Imperial's QFFF course as my first choice - I already have these offers because I began my final year this year but had to withdraw on medical grounds, and my offers have been transferred to start in September 2013 rather than 2012. I'm not naive enough to assume I know exactly what direction I will take myself, but I was wondering what sort of maths modules I should be picking based on my current path? The list is here: http://www2.warwick.ac.uk/fac/sci/maths/undergrad/ughandbook/year3/. My current drafted list contains "Groups and Representations", "Introduction to Topology", "Manifolds", "Essay" (I did the Essay module this year on my chosen topic of basic solutions in general relativity), and "Complex Analysis". I'm also hoping to take several modules from the Physics department and will list my current list of them if you wish to know. I know it's a fairly long first post and a lot to ask, but I'm finding it difficult to find the guidance here at uni of what to take, and was hoping you might be able to offer some useful advice. Also bear in mind that I'm pretty good at teaching myself some topics, as I have done in the past and had to do quite a bit this year since the medical problems I've been having stopped me from being able to attend lectures and seminars. I am willing to put in whatever work is required outside of lecture halls as well as in.
