Discard the text books and throw away those audio tapes. The quickest way to learn is with English private lessons online.

Having private English tuition is the quickest way to learn, but attending lessons in person can be inconvenient, while a private tutor can be expensive and difficult to arrange.

Taking your one-to-one English lessons online is more cost effective and easier to fit into your lifestyle. You can pick a lesson time that suits you and since your teacher isn't physically going to be there, there's no need to tidy up your room.
