<p>So apparently this year they are using the 5th edition which happens to be way more expensive. So I really can't use the 4th edition ?</p>
<p>You can, but some of the problems/sections may not be the same… and the Professors pull direct homework questions out of the textbook to use as quiz questions, but as long as you know the material, and the corresponding sections to lectures, then you should be fine.</p>
<p>They do pull questions strait out of the homework and fudge maybe one of the numbers, so its to your advantage to have the book.</p>
<p>Also, you might have to turn in homework, so it would suck to lose points on work that you did but the problems happened to be a bit different.</p>
<p>you can make copies of your friends books. or find a PDF of the book online</p>
<p>send me a private message with the book title and author i’ll see if i can help you out</p>
