I'm a 3rd year undergraduate in Spain contemplating continuing my studies upon graduating next year. I was initially considering doing my 4th final year via Erasmus exchange at Imperial College London so I could take some electives that my university doesn't offer. Unfortunately today I found out that I can't take any elective courses that aren't expressly offered by my home university if I go on an Erasmus exchange, which is really annoying because I wanted to get a taste of HEP courses (4th year msci in the UK) before going all out and deciding that's what I want to for a masters+phd at said institution. First and foremost, how can I familiarize myself with this area if my university isn't active in it? They no longer offer a final year course in QFT so I'm out of luck. Both the undergrad thesis program and the astrophysics department/grad school/research institute offers the ability to do a masters thesis in HE astrophysics which I can guess is only remotely related, but I'm not sure I want to do the masters in astrophysics anymore (2 years, required for phd, expensive and funding is flaky. Plus I don't really like the majority of the courses). What is the procedure for EU students wanting to do a masters+phd in the UK and what kind of funding is available, if any? What about academic records? Any help is greatly appreciated, thanks.
