Read! This will make a big improvement. I would suggest reading newspapers as the writing in there is usually grammatically correct. Reading can be very boring but it will always make a difference. People think watching movies will help you to improve and it might to some extent but the vocab you learn from reading will be far more beneficial.

I wish my english advanced to TOEIC 800 UP level , and i could listen, speak ,read ,write . that's all i need.

In wish level you are ?
