Hi!

I'm a Brazilian lawyer and I'm interested in studying in the UK.
Regarding Commercial Law, which LLM is better: Edinburgh, LSE, KCL or Glasgow?

Thanks in advance!

easily either KCL or LSE. i'd personally go for the LSE given a choice between the two.

You should look into course options and opt for the course that provides the modules that most closely fit with your interests. All of the options you mention have excellent programmes. If living in London is important to you then clearly you'll want to choose one of those schools. Otherwise, the Scottish institutions are excellent though Edinburgh's Commercial programme is a bit more established than Glasgow's.
Best of luck!

LSE.
