<p>for the class, the bookstore lists campbell's 8th edition of the text "Biology". do i need to buy the one listed on the student store or can i buy an older version to save some $$. the professor is powers. does she go with the book page-wise (giving me reason to buy the 8th edition) or is it just supplemental and not used as frequently (which would mean i can get by with using an older, cheaper edition...) thanks alot.</p>
<p>You can definitely get away with an older version.</p>
<p>oh sweet thanks</p>
<p>do we end up using mastering biology for either bio 1b or bio 1a/1al? i noticed its the same book for both so if i get an older edition i want to still be able to use it for bio 1a/1al when i take it next fall. i did find a couple old editions online but they dont come with a cd or mastering biology…</p>
<p>No, Mastering Biology is not used in Bio 1B or Bio 1A/AL. I suggest you just buy the older edition because it is a lot cheaper than the new edition.</p>
<p>alright thanks!!</p>
