“From my personal experience, anyone can learn vocabulary. Understanding a native speaker – now that takes time and practice. The more you get used to hearing the language, the faster you pick it up. It is like you stop trying to translate every word and start understanding phrases and concepts. I saw that happening more and more with each new lesson we did. In my opinion, that is just not something you are going to get from just a book. In five weeks, my boys already know more phrases than they have learned in the past year.”
