french demonstrative 3 skill will not strengthen
doesn't matter how many times i refresh i cannot get it back to full strength
I'm having the same problem. After doing it 3 times (there's only 2 sections in it!) and not getting a single thing wrong the last 2, I gave up and moved on to Adjectives 4.. and adjectives 4 won't strengthen either (though I only tried that one once. I don't see much point in hitting my head against the wall if nothing seems to want to strengthen.)
DrBimic told me to do the two lessons inside instead. Actually just doing the first one did the trick for me.
