<p>do i have to buy the custom UCI editon of the Bio93 book? If i get a used custom copy, is there a CD or any required web access key that would render a used book useless? thanks!</p>
<p>Nope and nope. When I took it 2 years ago, I used an even old edition of Campbell and Reece I wasn’t going to pay $40-60 for a book I already had with chapters rearranged.</p>
<p>Bio 93 is a custom UCI edition derived from Biology by Campbell and Reece. What the school did was basically assigned chapters specifically for the lecture. Just get a used one and your good. The CD from a new one isnt required.</p>
