I believe the best way to learn anything is by repetition and practice so my method would be less theoretical and much more practice intensive. Of course I can explain with detail the logic of certain grammar structures which will clear the doubts of the student, but I strongly recommend repetition and a full inmersion in the language and culture to achieve the best results.

Classes can be done onine or in presence (if the student lives in the surroundings) normally after 6pm.
Equipment is simply a phone or computer with camera and microphone. Computer is desirable as we could check learning material together.
During my learning I also studied parallel English at another institution and this caused both learning methods to mix. My proposal would be to use the learning material that the student currently has and develop on it so that one does not lose the connection to the main course.
