I agree with the many suggestions given by our friends. The core skill set to embrace any language is the passion to learn it. And I presume you have it in plenty, this is evident with the statement that you have made, about improving your English.
Watching English news on BBC, CNN, CNBC, NDTV etc., should also aid and equip you to pick standard vocabularies.
So the best way to judge your level of proficiency is when you speak to people, there is free flow of thoughts without hesitation / hiccups. In simple, clarity in what you intend to convey, which implies that you are a good communicator too.
I would like to tell you one very important ingredient for improving your English. Please avoid using SMS language as far as possible in your messages / mails / chats. You may be tempted to use them in your informal communication with your friends, that's okay and acceptable.
