Is There A Review Section?
Does the Flashcards bring up a Review section periodically, or should I just take care of reviewing my previous lessons as I see fit by returning to them?
The last lesson in the Learn Spanish series is a review lesson, but I don't believe there are any Review lessons on vocabulary. It's simple enough to just repeat the flashcard portion of any lesson if you wish to review. You might even raise your score (you cannot lower it).
