It would be helpful to have a feature which tests you on verb conjugation. kind of like the flashcards- but for specific verbs. I think it would really help with memorising all of the irregular verbs!
I agree -- it would be nice if the basic subscriptions came with some kind of practice exercises. I found a decent website that allows you to quiz yourself on various subjects in Italian ... but it would be nice if this site could include something like this as part of the basic membership. Personally, I find the lessons great but there's little to practice with; writing things out helps a lot.
