Hey guys ! For those who I can help, I took the TOEFL (IBT, that is to say on a computer) last year, and I had 95 out of 120, with everything above 20 out of 30 except the listening.
I can try to give you some pieces of advice.
For the comprehension, as you have 4 texts to understand and to answer questions about, you have to be very fast. I think they warn you and tell you how many minutes you have for the 4 texts, so divise it into 4 and try to stick with it. My best friend took it one or two months before I did, and she failed at this part because of that mistake, as she wasn't careful enough.
For the speaking, it's quite simple, but I thought that was an unusual test. You have a very simple question and you have to think and answer very quickly. The problem is that many people try to respond in a complicated way, but actually you shouldn't. When I asked my english teacher about it, she told me to use a very simple method : first, say a little introduction in one sentence (like veeery short), like you take the topic and turn it into an affirmative sentence (for example, if they ask you "what would be your dream job?", start with saying "If I had to choose a dream job, it would be...") Then, try to be a little bit structured. Answer with 2 or 3 arguments, and say one sentence for each argument, don't forget that you have not much time. For example, say "My dream job would be teacher; because (1) I love children, (2) I want to have long holidays so as to take care of my family, (3) I love teaching, actually I have a little sister and I'm always helping her with her homework." You can say anything, it doesn't really matter, even silly things that you don't believe
Then, end with a little conclusion. Try to be fast and to be clear and well structured. Maybe check on the TOEFL site to see what are the most common topics they give and how many minutes they give you to prepare your answer and then answer. I remember it was like 45s and 1 minute, but I'm not sure at all.
For the written part, you have 2 essays (if I remember well), same thing that for the speaking, try to be clear, not to make mistakes, and try to stay simple.
About the listening part, I think it was the most difficult part but my friend did it well and she told that she just took notes when listening to the documents and that she was very careful when choosing the answers.
That's all
