Textbook and Web-based Homework System 
Image of textbook
The text for Physics 21 and for Physics 19 is University Physics, by Hugh D.Young, Roger Freedman and Lewis Ford, 12th edition, and published by Pearson Addison Wesley. You will need only volume 2. For both 21 and 19, you also need access to the web-based homework system "Mastering Physics."  If you took physics last year and had an access code for MasteringPhysics, you can use the same registration again this year.  Your original registration is good for two years from the time of first use. 

There are several options for buying the textbook and the access code, separately or bundled together. The bookstore offers the following packages: a used text with no access code for $93.60;  a new text with no access code for $124.80; a new text with access code for $144.45. You can buy a new book plus an access code directly from the publisher at this link for $134.80. You can buy the access code for $56.80 online  at this link. If you order the book online, pay attention to the shipping costs and delivery times.  You will need the textbook when classes start.
