The Grunberg system of learning basic foreign vocabulary and grammar has hit the headlines in the last few months since it has been adapted for a range of computers. Dragon Data have produced a most creditable version which is supplied in a large presentation case with a reasonable instruction booklet and an audio tape as well as the program.
The system does seem to work when learning basic vocabulary; in a matter of a few hours this package rapidly improved my Spanish, which admittedly did not stretch far beyond ole and paella.
I found it easy to recognise and understand the words and grammar, although the system may not work for everybody. There are some 400 words to learn plus the basics of grammar. The program is divided up into sections, which load separately. The loading takes ages but is eventually worth it.
The program is certainly worth buying if you want to know a little Spanish before you take your holiday there.
