I know it's still a work in progress, but some of the later lessons (like past subjunctive in french) don't have enough sentences/questions so it literally will ask the same question 6-7 times in a row. It's nice and easy to get your points--but not very helpful to learning french
"It is good that you have been to the swimming pool"
Also, i've mentioned this before--but the multiple choices are way TOO easy. I don't even have to think or know the language...I just look for the sentence that has something in common with each of the two others. Or choose the two options that are the exact same but switch "ils/elles"
