Hello! You are very much welcome Tolly.
Regarding your plan to take an exam on the 18th pf Sept.
well ummm I don't want to crush your spirit and make you feel bad but I think we need more time. I mean if you really are aiming to get a high score then we got to give more effort. You know as I have mentioned, you can answer well when you have prepared especially with reading a passage and well at times with describing a picture, well with a few twists and corrections, you do have good answers. but with regards to answering questions, I think you should really give more effort in listening. you have to be keen in getting the right information or question so that you can directly answer what is asked.
make your brains work while the question is being asked get the key point and wham! exact answer! the problem is for example in 15 seconds to answer a question you already spent 7 seconds neraly half of it still thinking. that is really a problem and i think you know that. So you have to think fast. follow your intuition. because i know you can. one thing i admire about you is that when you say something wrong and you know it is , you correct yourself. that's great, gives an idea that you do know what you're talking about.
Well, I do think this trial exam will be very helpful. good luck!
