<p>Which would be better the Barron cards or the Kaplan ones?
I already have the Amsco book</p>
<p>It all depends upon what is on the cards. The new REA AP US History Crash Course book is much better than a group of random cards. Book is a systematic treatment of what you need to know. It is really helping me focus on what to study.</p>
<p>The SparkNote ones were actually a huge help.</p>
