I am presently interested in an intermediate level language cert (DELF B1), with books being a little "dry" for what I would like to use, thus maybe complementing (if not replacing?!?) them with some chatGPT assistance. I have been playing with various "conversational" prompts, as well as grammar and vocabulary flashcard-like approach to chatGPT, but can't find a fluent method, with consistent improvement tracking/progress monitoring. Would appreciate some feedback, from those having "nailed" this matter.
