I have never been very good at languages, but downloaded all four parts of this course in preparation for a recent family holiday to France. The method Paul uses works well, and I found I was able to make rapid progress after just a few days listening to the course on my way to and from work.
When on holiday I found I had the confidence to do the usual holiday things like ask for directions, reserve tables, order in restaurants and buy tickets for tourist attractions. I even surprised my family by stopping a passer-by in the street on the first day and checking whether or not I had to pay for parking in the town square!
It's a testament to this course that since returning from France, I have continued to listen to the final "review" lesson (part 4) to keep up the knowledge I've gained. Thoroughly recommended.
