There appears to be mistake on the part of the instructor, please feel free to contact PADI quality assurance (QA) with ALL the details, who, what, where, when ect. The e-mail address is
QA@Padi.com, I would also request replacement books.
From the PADI 4th quarter 2005 training bulletin for instructors et cetera:
"4. Knowledge Reviews for each Knowledge Development section signed by the student
(
You must either retain the student diver's completed and signed Knowledge Reviews or document in the student's training record that you have reviewed the student's completed Knowledge reviews. The Student Record File may be used for the purpose"
Note: Student divers can submit to you photocopies of their completed Knowledge Reviews if the prefer to retain the original in their manuals as a reference and study tool. You and your student are not authorized to photocopy blank Knowledge Reviews."
