I have recently completed my studies so I definitely know about how students feel during their lectures and would try my best to not to make them feel exhausted during lessons but they will surely enjoy by learning with different methods like exercises , games , quiz, conversational lessons...
Even I have learned Italian when I first came Italy, I was a zero in this language but slowly slowly by talking with my friends, learning with different methods I did it finally!!!
I would definitely try to make it easy as possible as I can.
About lessons I would like to call or via chat discuss with students or their parents about their timetable as if it matches with mine .
