<p>Hi guys,</p>
<p>I just went through both Volume 1 and 2 of Direct Hits (2011 Edition).
I noticed that there is a newer version (4th edition).</p>
<p>Is this book different than its predecessor? Should I get it?</p>
<p>Also, what additional books should I use to study for vocabulary?
I went through 1) Word Smart I 2) Direct Hits (I, II)...</p>
