Well, I just gave the test with 2 days of prep, I think my US XP helped a lot as I have been writing a lot of documents for my job here. Also, the Master's am doing requires me to write a lot of papers. For writing, just structure it in a way so that you are telling a story and don't bother using fancy words. Speaking was always a problem for me as am an Introvert, could have done better if I had the confidence. Rest of the sections, don't overthink, answers are generally the ones that are obvious.
