JPA questions in 1Z0-895 JEE6 OCPEJBD Exam

I have been following this forum and it is really helpful. I appreciate all the help provided by the members.

I am studying Enterprise JavaBeans 3.1 book for this exam. I know this exam does not cover the JPA. Can i exclude chapters 9,10,11,12,13 and 14 from studying for the exam. Also in Chapter 16, do we need to study Entity Manager Factory, Persistence Unit, Entity Manager reference starting from page 266? Also which chapters should I study from the EJB 3.1 Spec.
