I have to give this series some love. It is great if you've had some German already (I had 3 semesters) or pick up languages quickly. (Peter's review is probably on the mark, for the un-initiated.) It moves quickly and is very concentrated. Sometimes you have to listen to the same lesson 2 or 3 times. Having done a bit of the Pimsleur program I would say these 2 tapes cover the same ground as 10 or more Pimsleur tapes. If you want to brush up your German, or go from zero to 60 in a flash, "Drive-By"..I mean "Drive-In German" is a bargain. Too bad it's only on cassete.
