What should I do to improve my English?
 

im weak in english language so plz some one tell me what should i have to do for improve my english.

Grammar
 

First make a grip on basic grammar i.e oxford grammar, High school grammar etc then develop a strict habit of reading quality english text book, newspaper, book. It would help you a lot in sentence structure, style, tome, mode and application. Watch British english movies and also write down your ideas and compare it with standard writings.

@Rizwan.
Dont worry. U can be good at English. Act upon the given suggestion of the senior member. It will take time to improve. Read newspaper and collect vocab from there write in a copy by collecting synonyms.
Secondly, Learn grammar and use it in writings and get it checked from an experience teacher. In starting, write small paragraphs, no matter u making grammatical or spelling mistakes, keep doing this practice.
