ofc it is possible, u can learn decent german in like half a year Id say (decent enough for studying)
I came here at age 13 and needed 1 year for the basic language and 2-3 years more to do it. If you wanna stufy abroad go for the UK allthough its a shit country they have some good colleges (leeds for engineering, oxford and cambridge if your parents have a lot of money) and a linguafranca as a langage. Also considering some lectures are hard to understand as a native speaker I would recommend studying in denmark and doing your master abroad
I think if you already know the basics then you definitely can get to a good level in two months.
Tough, but should be doable if you really apply yourself and learning languages isn't like your kryptonite.
Start by study German where you can - for instance watch German children's TV-programs, take your summer holiday in Germany and so (it is a great country so loss in doing your vacation there).
German is easy to learn. So go for it. But honestly? It is way better to be really good at English than German in pretty much every situation unless you specifically want a job in Germany.
As a Dane it should be pretty easy.
I started my study International Business and Languages which includes the german language for me as well. The uni started with the level of german that I (should've) been thaught in high school, except that I'd never had german in high school. Currently in my 2nd year and doing pretty good so I think you should just go for it
Why don't you want to study at CBS? I think learning German is pretty challenging, especially the cases. And if you're studying International Management, you might as well study in an English speaking track, whether in Germany, Denmark or elsewhere.
I as a german have to say that it's probably one of the hardest ones to learn. But ofc it's doable if you put enough effort in it.
