have to hand in the originals not photo copies , that way the book cant be used /resold again padis way of making you buy new each time
This is not required by PADI. As Jack as stated above, the recent (but now changed?) requirement was that students must have their own copy of the book, they must complete the KRs, and instructors should keep a copy of the completed KRs in the student's file. Many instructors interpreted this as "rip the KRs out of the book and hand them in." I always thought that was ridiculous... why insist the student had to buy a book if you won't let them keep all the information in the book? The KRs are their work that they will hopefully refer to later.
I made a habit of making copies of my students' completed KRs when they worked on the final exam. I kept the photocopies, they kept the originals intact in their books. Standards met, no ripped or missing pages, everyone was good.
But to the OP, that's going to be a "no". Live and learn: when you buy a used book, sometimes you'll get what you pay for... i.e. essential parts might be missing.
