I think there are universities in the Netherlands that teach in English, because I have heard about students from the UK studying in the Netherlands, and most people here are very slow language learners.
If you were to go to the Netherlands to study, you should try to learn Dutch while you are there. You could learn a little, a few key 'courtesy' phrases, before you go, which would be appreciated, as it shows a willingness to make an effort.
I also consider myself a slow language learner. However, even though it takes a bit longer, that doesn't mean you can't do it.
What I highly suggest, is that you at least start with Duolingo. It's not the most amazing program in the world, but it only takes about 5 to 10 minutes a day and you'll learn something:
And yes, almost all of us Dutch people speak English, and most of us love getting a chance to practice it, but you won't get the full Holland experience without trying to learn at least a little bit of the language. I went to study in France and hardly spoke a word when I arrived there, but was fluent when I left. It makes your experience so much richer!
Enjoy your stay in Holland! :)
