??? There are _official_ prerequisites for a class. A student is not _allowed_ to take this class without having passed those other classes. All the author of a book can do is explain what audience he had in mind  he has no control over who actually reads the book.
What's difficult about finding out what the students know? After the first quiz in differential equations I can tell you which ones know enough calculus.
Your, erm, experience must be vastly different from mine; in particular the rules and regulations at the place where you teach must be very different.
"exactly the wrong way round" indeed.
