lessons

I don't understand why I have always the same lesson on the move the rook after I did it (even if its totally useless for me... if someone knows how to avoid that, thanks!

Maybe you should ask your question in French and someone (not me) will be able to help you?  In English, it just doesn't make much sense.  Maybe if you just gave us a little more information?  Are you possibly talking about Chess Mentor lessons?  And what platform, mobile or computer?

thanks baddogno, sorry for my bad English....the problem I try to resolve is about the lessons on this site, because normally, they are differents each day, after you have resolved the one of the day. But instead of that, I have always the same lesson since 4 days, about how to move the pieces. I am using a Samsung tab...
