<p>My B&N list of books and supplies includes SparkCharts. Do I really need to get these, or can i just find the same info myself for free online?</p>
<p>If I need to get them, should I ask for them used @ B&N?</p>
<p>Haha my mom just got them for me anyways since they were only 5 bucks a pop. I used to have a sparkcharts for Trig way back when and it was great because it had ALL the highlights of the subject in an easy to read format. Plus, it was all in one place and so easy to use as a refrence.</p>
