While I am still on Level 1 of Rocket Spanish, I am not only enjoying it but more importantly, I am actually learning to speak Spanish. I've been going over and over each sub-level until I am totally comfortable with everything - works for me. I am 67 and planning on moving to a Spanish speaking country in 2021, so naturally, I want to be a bit prepared.
Also, I am finding all of the optional exercises enormously helpful; I need to see the words and write them in order to lock them into my mind along with the meaning and pronunciation. I understand not everyone learns this way but I chose Rocket Spanish for this reason - along with the fact that they generously allowed me to try out the program first to see if I liked it. I love it!
I also plan on getting a few Spanish short story audiobooks and listening to Spanish-speaking podcasts once I have progressed more.
Highly recommend!
