In reality this work relatively well, keeps a traditional approach to learning. A combination of mix, vocabulary, grammar, pronunciation ... in which we find the same tedious aspects that could be criticized for conventional approaches.
I am nevertheless satisfied because it allows me to have a more theoretical approach of Spanish and understand why and how we say things. I pair this book to another method that is completely based on hearing and repetition (more original approach, without study, which leads to speak a little Spanish from the first lesson). The mix of these two approaches is a cocktail that suits me well.
