<p>Which Sparknote Power Packs actually work for cramming for AP tests or for self-studying purposes?</p>
<p>I liked the US government flashcards...but I didn't use anything else in the pack.</p>
<p>bio was decent.</p>
<p>The European History cards were amazing. I took the 2006 exam... my teacher literally didn't lecture a single day all year and the last chapter test we took was on the Renaissance, and I got a 4.</p>
<p>In my experience, SparkNotes is horrible. It and Kaplan vie for worst test prep company. The information they present is well and good, but rarely is it actually tested on CollegeBoard exams. Just for purposes of credibility...I used Sparknotes for SAT II Bio, SAT II US History, AP Chemistry, AP Euro, and AP Bio. Stay away from Spark</p>
