I'm learning five languages at the moment: Portuguese (my native language), Italian, English, Spanish and German. My advice areI have two: 1) make sure you really learn the languages and 2) use the languages once in a while, your brain needs to remind itself pieces of them otherwise it will forget.advice:
- make sure you really learn the languages and
- use the languages once in a while, your brain needs to remind itself of them otherwise it will forget them.
I think the second advice is very clear but I'll explain the first a little more. Basically, it's not because you said you're in a certain level, that you actually are. For instance, I have this colleague at university and he says he's fluent in English but doesn't know grammar, now, can he really be that fluent? Grammar, despite of what many people think, it's not just a bunch of rules invented by a couple scholars, it actually explains the language pretty well. Now, how can knowing a language better help you remember of it? Simply, you remember more what you know well. Do you still remember the content of one of your school exams? Probably not and if so the reason is not only lack of revision but lack of understanding. Hope it helps :)
