Well, the area that were more successful were "reading". I think that see the word is less difficult than listen. I used "wordreference" hehe, but anyways I think it's more simply. The exercises didn't be difficult. The third exercise was more complicate, I spend a lot of time in this.
In the other hand, in the listening exercises, I had many problems.The first exercise was very simple but in the second exercise I can't understand a lot of thing. I think I should practice this.
The vocabulary exercise was not difficult, however I used the wordreference sometimes
