I have used the Puerta del Sol program
personally for comprehension practice,
and I REALLY like the program. It uses
Spanish from Spain and takes some
getting used to, but the programs are
very well done. Tim Keller, President,

Interactive conversational and
workplace Spanish materials for
classroom use & self-study. Designed
for the adult learner more interested in
communicating than grammar rules.
"the best way to learn a foreign
language is to be in the setting where
the language is spoken. Progressive
Language gets you as close to that
experience as possible. The language
and culture are brought to you."
