Act book choice help!

<p>I am a junior in high school, I am planning to take the ACT soon. I am not quite sure when is the best time to take it, can someone please give me advice on which month is best to take it? I also want to know of a good test prep book that will significantly help me to get a better school!
thank you!</p>
