| Issue | Tip | |-------|-----| | | The original book comes with a CD/app. Many free PDFs lack audio – you’ll miss pronunciation and listening practice. | | No interactive writing space | You’ll need a notebook or digital annotator. | | Some cultural references dated | A few examples mention CD-ROMs, Minitel, etc. – but vocabulary remains relevant. | | Not for false beginners | You need at least B1 level, or you’ll struggle with the explanations (written in French only). | | PDF formatting issues | Some scanned copies have blurry pages or missing accents. Try to find a clean, text-based PDF (not image-only). |
