Yo se espanol
I already know a decent amount of Spanish, is there any way to skip to harder lessons to practice?
There are a few trophy icons in between large chunks of lessons in the skill tree. You can click it and take a test to unlock everything up to that point.
Be careful, because you may have gaps in your knowledge of Spanish, and not even know it. I know it is cumbersome to slog through familiar material, but you will be surprised when you discover "holes" in your Spanish education. I learned this the hard way working through Khan Academy.
