I am trying to learn a language and thus found this offer intriguing, but know nothing about Pimsleur, For anyone else interested, here's a link to Pimsleur review:
When I was assigned to a Latino area school in 1966 I immediately started trying to learn Spanish. I did 3/4 succeed, enough to be assigned a bi-lingual first grade. I loved teaching beginning reading in Spanish which is phonetically logical and consistent. Almost all of my children did well. When I retired in 1983 I used Pimsleur cassettes in the car to maintain as much facility as possible. I thought it was an excellent program which I can strongly recommend. I don't know how it would compare with the newer computer interactive programs.
