@michel_75 I totally disagree. The English test is just a basic grammar actually. We only find it difficult because of the time constraint. If others can do it you can do it too. Set a goal, work and pray hard to achieve it.
There is one thing I did during my second review. I have a tendency to stutter whenever I speak English. I tried to research what caused this mannerism. I found out that's because we tend to translate from our mind the native language we learn to English. So our mind is working simultaneously. Hence, we run out of next words to say. One youtube channel "English anyone" suggested to try listening native speaker how they talk and what words they used. native speaker just talk and disregard grammar rule. They learn english from constant conversation not from grammar books. So that's what native speaker suggesting learn from constant conversation not from the books.
Since I don't have time to talk to native speakers I did "shadowing" (I learn that in youtube too. ) I tried to imitate the one talking exactly what he/she is saying. I tried it for 1 whole week. Whenever im watching CNN or BBC, I tried to imitate the reporter. Though I don't catch everything he was saying at first but gradually I was able to repeat everything.
I believe that helps me in getting a 79 PTE score in speaking from 66.
