Spanish Bases, explain theory and practice with non stop exercises from the easiest to the most difficult

I know how to speak Spanish, I've been traveling through the country for the last four years and I'm moving there next month. I also studied foreign languages so I'll make sure everybody have the same education I had of the language.
I'll make sure a lot of exercises will be done ! Studying a language through practice is the best thing !!!
I never teach a language to someone else but if it will happen, I'll make it simple and understandable for everybody
