Is it easy?
Of course not! I hear you! You have so many students at different levels, so many preps, and tons of administrative tasks. Also, there is a lack of interest for a lot of students when it comes to learn a second language, and a lot of administrations don´t understand Second Language Acquisition.
It´s not easy and I don´t have a magic pill. But I can share and give you support just like my great mentor Mrs. Morales did for me. We also need to have grace and patience but it can be done.
