4 years of experience in teaching English language to the students

I am a student pursuing masters in International Business in Grenoble ecole de Management. Teaching English is something I did for the past four years during my bachelor's degree.
I use to teach English to the large group of students (Minimum 20 and upto 400). I designated as the Secretary of the Engish Proficiency Club in my University. And I like to see pupil benefited via my classes. I wish I should continue teaching for the well being of the learners and which makes me satisfied.
I prefer teaching face to face rather than teaching online. But in case of online teaching, I can do my job without hesitant.
