A buy of course with the Little Grévisse as icing on the cake, exercises direct reference to paragraph grammar book that explain the concept. It really is VERY well designed.
One regret me take away a star: the CD-ROM that contains the answers. Impossible to correct other than his computer is a practical ... Besides the CD-Rom is not readable on Mac OS X 10.6, as formatted PC. This is even more stupid than them in PDF files are searchable by vulgar n "any interface.
But this last detail, the exercises are really ideal for school and university students who want to refine their knowledge of French. Some are very simple, others more complex, and ultimately even people deemed "good in French" are material to scratch the front!
