Errata
Sometimes we make mistakis mistakes 
Text Revisions
In order to continue to provide quality products, we recently revised all of our texts, workbooks, and teacher’s manuals. As of August 2010 we have completed all of our text revisions. If you find an error in one of our products, please contact us at errors@gravitaspublications.com.
However, if you have purchased an edition earlier than 2010, there may still be errors. Below are Errata files in PDF format. Just click on the one you need and the page will either open in or your browser will ask you what you want to do with it. Simply save it onto your local hard drive. Please make a comment if there are any issues getting these files. We try to keep these updated, but let us know if you find any mistakes that are not listed. Thank you.
