Overall Rocket Spanish has been outstanding. I like how they teach Spanish and how they use the previous lessons to build upon the next lesson. I like the review at the end of each lesson to help reinforce what you learned. I also like the fact that the words are shown in the lesson. Seeing how the word is written helps me to pronounce the word correctly.
I wish there was a way to click on additional information within the lessons about certain words and their use such as Estoy vs Soy and Eres vs Estas. I had to Google those words to understand when it is appropriate to use them so that I would understand and remember.
I started using the phone app and playing the lessons through my car speakers as I'm driving. I love having that capability.
