Let me help you with your entry. Your English is actually pretty good. I'll try to rephrase some lines to make it appear more natural.

As to your question, I believe that practice is the best method. You can accelerate your learning by using the language in actual day-day-conversation.

This writing is about my biggest problem that is speaking of English!

Hi Everyone,

I am Gül, from Turkey. I have been learning English for a year. My writting is better than my speaking spoken English. Because while When I start speaking English, I begin thinking of which about what tense to use and I just get blanked out - without any word popping up in my mind as if my level is I were beginner However, I go to the English Course although in reality, I am upper-intermediate as guaged in the English course I am attending level there. :((( How can I climb this over? (Or you can say - How can I top it up a notch?)

Thank you in advance,

Gül

Hi Everyone,

I am Gül, from Turkey. I have been learning English for a year. My writting is better than my speaking. Because while when I start speaking English, I begin thinking of which tenses I have to use or I no words don't come to my mind any words.[my mind goes blank] As if my level is beginner. However, I go to the English Course, I am upper-intermediate level there. :((( How can I climb this over? [overcome]

Thank you in advance,

Gül

Merhaba Gül, I suspect the only way is to talk to someone English!

Maybe I can help?
