Well, the good thing is that there are many entertaining options to learn English, out of norms to study a lot of texts, (out of norms: fuera de lo común).
If you really want to learn and prepare yourself for a new opening of the year, towards* the Winter, just contact me.
I am waiting for your decision to make mistakes learning English: (verb +to/verb +ing. form)
(cometer errores aprendiendo Inglés), because if you do not make any mistakes, you will never improve your skills.
