Can You Use the Easiest English System as a Total Beginner in Other Languages?

Is it possible to use the effortless English system as a total beginner in other languages? My courses are focused on intermediate-level learners. I'm using this system finally now with Spanish. You can also just create your own learning plan, independent learning plan for any language. And if you do go to an English class or an English school, what is the purpose of that class for you?
