i am not a native english speaker, however, i like english very much, when speaking english, i feel so proud. many years ago, my english is very poor, yep, very very poor. when my mum told me that i will have to had a english test before i enter highschool, i make up my mind to study english well.

but, i learn english through many unformal way, i hate vocabulary, i hate grammar, so, i hate english class, but i like english songs, english movies, i watched a lot of english movies and became the super fans of WESTLIFE, which is a famous boyband, indeed, songs and movies help me a lot, especially oral english, now, i am proud of my oral english, i obtained many prizes. and people do think that i am very good at english because of my good oral english. however, i know they are wrong. actually i am not that good, i am lack vocabulary, and always make grammar mistake, i can not talk about a particular topic in depth, i feel so shame. please tell me what can i do? how can i improve it?

I really don't understand your question but your english is better than most americans.. Find something you like and then do a report on it in english..I think your grammar is fine and im sure there are schools that you can learn better english at even on the internet..But really I don't find your english bad.. As I said its better than most americans or english speaking countries .so what is there to be ashamed of..be proud.. you speak very well and also write very well

Your English is much improved, perhaps better than some who were born here.
One good way to improve English is to read books. Follow the grammar and the way sentences are worded. Pay attention to what words are used together in sentences. It will get better just by seeing it in print. Little children learn sentence structure by hearing it from adults and you can speed up your learning by reading books.
Keep up the good work, you are doing fine.

Try reading. It's a great way to absorb both vocabulary and grammar. Anything would work... I recommend fiction for your age group, or autobiographies.

You're English is very good already though, so you have a good start. Congrats and good luck!

wow.. your English is so...so wonderful. What else you want more ... and more....

well, reading what you have written... I say your English is very good!
You could always take a class. I know here in America there are many free classes to help people with their speech and English writing. Not sure where you are from... but you might wanna check out some free classes.
(but I don't think you really need one! Just keep practicing!)
