Question on AP comparative govenrment. Use study guide as a book?

<p>Hello~</p>

<p>in my school, they put AP US Gov and AP Comparative together into one year long class, so we learn US gov 1st semester and Comparative 2nd semester.
Today is the start of the new semester and my teacher told us our AP Comparative government book is Ethel Wood's AP Comparative study guide. <- that is our course book. </p>

<p>So I'm wondering if that's enough to study, my teacher homemade a study guide to go along with it..</p>

<p>thank you.</p>
