I need to buy the textbook for Math 1A03. My prof suggested to buy the package that they sell at the Titles. But, I want to buy things cheaper and want to buy used ones. I was looking on the Titles website what the package comes with. It says: Custom calc ET + CALC LABS + 2X SSM + EWA + MAPLE 15
I assume that custom calc et is a text book? and I know what maple 15 is. But other than that i have no idea what calc labs, 2x ssm and ewa are. Can anyone tell me what they are please??
Thanks in advance!

That package would come with the textbook, two student solutions manuals (SSM), and I believe that EWA stands for Webassign, which is basically an online math quiz that goes along as part of homework... it may/may not be optional, but I recommend it because I believe it takes some % worth off the final.
