My Italian level says 9, but I've been on the same 15 words since the earliest levels.
Is this as it should be? I know I had a lot more going on in French level 9.
The level goes up with how many xp you earn and has nothing to do with how many lessons you have learned. Although you do earn xp when you learn lessons, you also earn xp when you review lessons. They have decided to change that a little and now we will earn less for reviewing than for new lessons.
You're right, 9 was my French. I remember how much more complexity there was in French on Level 7. My vocabulary has had no new introductions for many levels. I'm learning nothing new.
