Not sure
Can't help but think it's a bit rude to go and live in a country and not learn the lingo.
Ja, Nederlands is heel moeilijk dat klopt maar jij woont bij Nederland nu! Veel success.
A year of living in the country should get you fluent. Sorry I can't think of anything more productive! Is it not possible to do the exams in the UK and have them count? I suspect probably not?
