Ap Micro/Macroeconomics 5 Steps to a 5, is this book effective?

I am planning to take the coming economics test. Is this book enough to get 5, even if it is the 2008-2009 edition? If I have enough motivation, will I be able to get enough preparation from now until the test day (btw, I am self-studying)?which one should I choose, micro or macro? what is the deadline for the international registration, I can’t find it on the website ?</p>

if you know the answer of any of these questions please help,</p>

<pre><code>thanks!
