They will be returned to you at your lecture final. Photographs, if labelled, may be acceptable although do not fulfill the intended purpose as well. Get my permission before you do this.

Organization does contribute to the final score.
Within that basic organization, perhaps start with the handouts, then the questions and notes then the drawings and then the quizzes.
