As an English teacher teaching in Turkey, I know English is so important for your career rather you want it for travel or mostly for a good and high position in your own country.
SO, Why dont you study 7 hours per a week in ONE month !!! You can Improve your speaking skills and communicate Well + Having your IELTS in your pocket in a very short TIME!!
I had helped many students from different countries mainly Turkish Student to have their IELTS With a good score.
*Therefore I Have worked as a native English teacher at American Culture school.
