Spanish as a foreign language (DELE)

I had opted for an individual lesson; therefore, I was of course always alone in the class.
One of the two teachers suited me very well. The lessons I received from the other teacher were not okay according to my point of view; it was also the reason why I decided to cancel the last two lessons.
The book itself wasn't brilliant either: no organization and very difficult for someone who knows nothing of Spanish. There was never a repetition of the lesson before, on the contrary, you had not yet studied the new words and new ones were already appearing. It is not a good way to learn a new language.
I returned home very disappointed. In the meantime, my enthusiasm for learning Spanish has dropped below zero. Sorry to be so negative but it is my experience, my opinion.
