Hello. Please help me with the schools. I have an offer from UCD Msc Finance and ESMT MiM with a scholarship of 10000 euros. What should I choose? I don't know german but i am ready to learn it. I am a fresher.

It's going to be virtually impossible to pick up enough German in 22 months - alongside an intense MiM program - to develop professional fluency in the language. Your career outcomes would probably be better with UCD, especially considering that school's placement in the FT rankings.
