The text hybrid printed on the book is a fallacy: it suggests that it has something more than the normal issue. Unfortunately, the opposite is true: this book does not contain the exercices!
Instead, at the end of each chapter you will find a text that you can get them on some web page, which requires registration, and they kindly guarantee that even if you fail your exam, you will be able to access exercices next year.
In my opinion, a physics book should contain exercices that a student can solve using paper and pencil. Password protecting them, and making them available only if the student has online access greatly reduces its usefulness.
