I would like to recommend an intensive language-training course offered by Care Force.
Within a few weeks of on-site training in Holland you get the opportunity to thoroughly learn Dutch grammar and important part of Dutch vocabulary. It is, of course, a kind of challenge for a foreigner to come to Holland for language training. It is also obvious, that one can’t master a new language in a few weeks. But this training is a very effective one and progress is fast and substantial. After the training you get very strong language foundation and this, in my opinion, cannot be achieved in such a short time with other methods, like home-based learning or self-study. The course itself is run in a reliable, logical and very friendly way. I honestly recommend this training for those who still hesitate.
