M211 textbook?

<p>I saw someone selling M211 textbook(Single Variable) on Onestart, but the book she got is "IU edition" and the ISBN is different from the one on IU bookstore. She told me she used the book for both M211 and M212.</p>

<p>Should I buy it? She's selling it for $45, does it worth it?</p>

<p>Thank you</p>

<p>If it’s not the book you need, why would you buy it?</p>

<p>cause she said she use it for both M211 and M212</p>

<p>It looks to me like those two classes use different editions of the same book.</p>

<p>Get the book your professor wants.</p>
