Imperial Business School vs WMG Warwick

I think they are both equally reputable universities so it's a really tough choice between the two. I don't know much about WMG but WBS certainly has a good reputation.

If I was in your position I would choose based on the location. If you go to Imperial you'll be in London and probably get more opportunities for networking and finding internships.

Which field of work are you hoping to go into after you complete your MSc? That might help sway your decision. Have you been to visit the universities or had video tours/phonecalls with the admissions departments? Talked to any current students on the courses you're looking at?
