I have learned English for four years now and for me the hardest things about it is to remember and use new vocabulary. Ok, I got new ten vocabulary that I am happy with that but I will forget most of them for tomorrow. It is really desappointed consantlly and frustrated. What I do in order to remember is write them down on the some piece of papers and put it on the wall where I can see a lot like in the kitten, in bathroom... everywhere!!
