I am interested in LLM in one of the top 5 UK Universities :
Oxford, Cambridge, LSE, KCL or UCL

I saw that LSE, KCL and UCL require Undergraduate degree with high 2:1 honours which I've got, but I don't see any other mandatory requirements other than TOEFL.

1. How could I estimate my chances to get an offer from at least one university from this list, and understand if it's a goal that can be achieved or just a waste of time?
2. What are my chances to find a job in an English speaking country, or in a global work place after LLM? I have a citizenship of the EU, but my LLB is not from the EU/UK or an english speaking country.

Many Thanks!
