<p>So, I need to brush up a little on my vocabulary and was wondering if it's necessary to get both of the direct hits books? One of them is for core words and one of them is for the "toughest words".</p>
<p>I got them both.
But personally I think they should only go with one book. Making them 2 volumes is a simple way for the publishers to make more money.</p>
<p>I also got both.</p>
<p>lol it annoys me that there are 2 and that they are each 15 bucks...but i guess it is worth it - it does sooo well lol</p>
<p>but korean sat ii book is even worse...it's one thin volume and 30 bucks
guess it depends on how many people will buy it :)</p>
<p>I bought both volumes on Amazon for 13.45 each. They are awesome!</p>
