New REAL ACT Prep Guide?

<p>I have an incoming junior in high school and he wants to prep for ACT this summer. Does anyone know if there is a new edition of The Real ACT Prep guide coming out for 2015 or is the 3rd edition that has a 2011 publish date the latest version? Wondering if the ACT test is changing and if the current edition out going to be relevant.</p>

<p>Thanks for the info! Exactly what I needed to know.</p>
