Total Registration gives you the ability to download your data for use with Microsoft Word's mail merge feature. This tool allows you to download an Excel compatible file to use in a mail merge document. This document includes the student's first and last names, student id, email, and exams they are taking. Many schools use this to create labels to be used on envelopes or folders to organize the student's testing information, answer sheets, student packet, etc.
Different versions of Word and Excel differ in their specific instructions of mail merge. Please search Microsoft's help section for specific questions/issues regarding your version of those programs if you have questions using mail merge.
