This script gets the Chegg solutions for any given textbook and outputs all of them to a simple html document. It is intended to be automatic, once I get it to work that way but for now you can:
Find a textbook you want all the solutions for and navigate to the first question in the first chapter. In chrome console, copy/paste the two functions at the top and enter them into the console. Then follow the directions in the script.
