Well recently I got subscribed to GoEnglish to improve my poor English a little so because of reasons of work and computers I need to be better in this language and I think I’m doing well, this school is incredible not just because all teachers are from different country’s it’s because of the system that they use, they focus a lot in the pronunciation and the accent and also in grammar so I hope with time be a better speaker so I can make me understand to other people in other countries,
Other thing that I would like to do is to study a doctor’s degree (I don’t know how to say “doctorado” in English jjej) in a university of USA so for do that I need to pass the TOEFL exam at least with 500 point I think, im not sure I’m going to do a deep research.
Here are some teachers..
And some of the students 
Cheers!
Ph.D (Doctor of Philosophy) = doctorado
thank you rafa, that was very useful!
