This is what I recommend you to study english.

When i was in Canada, i used to study english at the following site. 


1. Go to the website

2. Begin with "Short on-line dictations."

  • Click A to listen first at normal speed. Do not write anything yet.
  • Click B Listen at slow speed and type what you hear in Box C.
  • Click D to listen @ normal speed again and make corrections in Box C.
  • Click F to see the transcript and correct your dictation.

Finish all the Short dictations.

3. Do the "medium on-line dictations."
