I've been at 71% for weeks. Doesn't seem to matter how much time I put in. Any suggestions? Am I just making too many errors?
Yes, I suggest you work with podcasts. Listen to them, translate them, etc. Here are my two favorites:
That's over 200 podcasts, around ten minutes each, with transcripts. After L'Avis #108, and all of Balades podcasts, there is an autocue feature, so when you click the text, the MP3 starts there. You can repeat phrases over and over, until you have them down.
