Unique approach
Very useful to study most common words. Favorites list allows one to focus on personal needs and work around the initial heavy emphasis on words that function more like peripatetic and prefixes and have multiple meanings. Flashcards or the ability to remove words that one knows would be helpful for learning. Also lists or subgrouping options would improve a good concept. Russian language has many endings so vocal approach only helps for a short part of the journey but certainly provides an essential part of that journey.
