I have a lot of confidence in my ability to understand/write/read french and I want to get ahead in the summer. So I was looking for some advanced french text books or foreign language books about french but for either an intermediate or advanced learner.
I've found Grammaire Progressive du Francais / Niveau Avance on Amazon, but so far no other books.
So, my question is: Has anyone used Grammaire Progressive du Francais / Niveau Avance and it is good? Or can anyone suggest another book that may be helpful?
Thank you in advance!
