I am just beginning my Spanish studies and I have found the Pimsleur Conversational Spanish Audio program to be a great asset to my curriculum. I am pairing the audio CDs with online studies (Rosetta Stone & Duolingo) as time allows. The best feature of the Pimsleur program is convenience. I listen to the lessons on my commute to and from work and feel I am absorbing much, if not all, of the information. Again, my studies are in the early stages but I feel I have learned more Spanish via Pimsleur's program in the first month than I did throughout 2 years of Spanish classes in High School. I highly recommend this product to anyone looking to break into a new language.
