I never had a formal English education, however I taught myself this language by watching many movies and playing a lot of online games for almost 3 years while I was in high school.

when I attended the college and found out that all courses are being taught in English, it made me improve my Academic language and increased my vocabularies in the language However even that I'm good in reading, I can't speak very well because I can't call the vocabularies from my memory or write with a pen and paper because I will have tons of spell mistakes, I'm not very good in listening too My biggest problem in this language is when to use a specific preposition such as in, at, for, from, to... etc. I hope you correct this text and use better vocabularies if possible Thanks in advance :)
