Yep! There are by-default reviews included with each round. Pro users can change the number of reviews per round as well as manually set sentences to 'Mastered', or ignore them so they're out of your queue entirely. I'm also working to get a 'Set all sentences with this missing word to Mastered' added for Pro users within the next few weeks.
