If you want to test your English you can send me a piece of your writing about any topic (e.g. tell me about you, your job, family and friends, etc., your hobbies and plans) no longer than 200 words. Sign up,then sign in, and use the ask questions option in this blog. I will have a look and let you know what I think of your current level of English.
If you want a more objective view, go to this website and do the test:
