My TOEFL is Near!

I know I am not the best in English but I understand many things, and my university demands to me that I complete a toelf TOEFL  exam in order to graduate me. Really, I have fear I am really afraid because many friends have told me that this exam is very complicated, and it have has many scientifics articles and technical vocabulary. and... Well, I have many problems in writing, including part grammatical grammar and in the vocabulary.

The English is a beautiful language, and the person people that speak this language are beautiful too. However, this exam is not! Yesterday I did the simulation (or "practice") exam, and my answers are were terrible! The minimal point grade for to pass the exam is of sixty points and my result of this simulacre practice exam was twenty-eight points. It is a horror! 

In the reading exam, I am was not able to concentrate because my corset was suffocating me and for this reason I cannot couldn't breathe, and I lost many minutes being unable to concentrate. desconcentrate. ("It was suffocating me" indicates that you couldn't breathe, so you don't have to add that.) I think that maybe this affected my practice exam simulation. After, the listening was very difficult, because it was a teacher speaking about astronomy or philosophy! Oh, that was complicated. I dont didn't understand anything and the questions were very specific.
If the listening was terrible, then the speaking was worse. I understood the question but I could not organized my ideas. Huh...
it That is all for today and thank you for reading my text. me

Good luck on your next exam! Maybe you would feel better if you didn't wear a corset to the exam?
