I'm studying english on my own, and I find this book, and the exercises one, to be very useful; the explanations are clear, and so far I think I have understood everything related to past, participles and continuous tenses.
The CD-ROM contains the same things as the book, more or less, and a few more exercises. The price difference between this book and the one without CD was so little that I bought this one, but the Cd is not essencial.
