<p>Principles Of Economics (ucsd Custom), 4 Edition, 9780077299316
*Principles Of Economics W/ Connect Plus Code (ucsd Custom), 9780077960902</p>
<p>These are the two required texts for Econ1, does anyone know what the second one is and if the text (besides the connect plus code) is different from the first one? I asked someone who took the class last year and she said the second one wasn't on her required list before, so I was just wondering if I really do have to buy it from the school bookstore.</p>
