there are a few things that i like about these CD's....
1. the teacher, michele, has a great accent, and he really does correct the students' pronunciation & stress as they make mistakes, slowly enough so that you understand how to make the corrections, too.
2. there is time for you to answer michele before the students do (though if you really have to think about the answer, you'll get cut off by the students--easily solved by a pause button).
3. michele does explain what needs to be explained before diving into practice, though it is often a quick explanation, meaning that this should either be review for you and you wish to get a little practice in, or you are also looking at a book to help explain further (though this is in contrast to reason number 4...)
4. these are good for when you are driving, because there is no book, and
5. a good intermediate level on the first 2 CD's, and an "intro" to advanced on the last 2 CD's...with a 5th CD being the ultimate review of the first 4 CD's with no students.
and a few drawbacks...
1. there is no book to go along, so i doubt that this will help with writing and reading too much (though michele does make attempts to verbally explain certain spellings). i would say that these CD's are primarily for speaking and accent correction.
2. it is not entirely advanced, so some may be disappointed with the level of instruction & difficulty.
3. i highly recommend a vocabulary supplement; these CD's give you the ultimate structures upon which to build sentences, but if you have a limited vocabulary, the only things you'll be saying are "I didn't buy any because there weren't any," and, "I lifted myself up" vs "I lifted it up."...Not much content in there.
overall, a decent purchase, but you will need supplements, i imagine.
