I am going to give you a diagnostic of your English by doing an indicative level test, based on the Common European Framework and my experience as EFL teacher.
In order to detect your English level, you have different options: sending me a short writing that I am going to propose, having a short oral interview by skype or on the phone. That will allow me to evaluate your English level, taking into account your writing or your speaking skills, which are the productive parts involved in language learning.
The more sample of your English I can gather, the easier it will be for me to give you an approximate diagnostic of your English level.
What are you waiting for?
