The History window can be viewed by selecting the History item in the Pupil menu or by clicking the See My History button in the main test window. The first tab, Results, shows the results of the last drill you did and your status on accomplishing mastery minutes for that one drill attempt.

Mastery
The second tab, Status, shows the progress to mastering the last drill attempted.
See 9. Lesson Plan

Statistics
Lots of interesting facts are kept here. Just keep in mind that the left column is only for the last Drill you took while the right column is either accumulations or averages of all the Drills recorded in your Log.
Log & Graph
The Drill Log displays the test, number of words, the score, date and time. The Drill Log will hold up to 500 drill entries and then start rotation of those entries if any more drills are done. The oldest of the Drills recorded will be removed.
You may save the Drill log as a text file. The resultant text file will be tab-delimited, meaning that the tabs will be set so that you may arrange the columns in a word processor or you may import the text file into a spreadsheet easily.
The Graph gives a visual indication of how well you are progressing. You may remove some of the clutter of the lines by unchecking boxes for Accuracy, Error Rate and WPM. If you would like to print the log without the graph, uncheck all graph boxes before printing.
The Graph and Log are printable together using the button in the bottom right of this window.
Key WPM and Key Error Rate
Both of these panes have graphs that provide information that you might find helpful to evaluating what are you strong keys and which you need to work on. These graphs only evaluate the last Drill you took.
