As illustrated below, the **TestDays** tab shows an animal's previous testdays (in order of oldest to newest) and the key results from each test.

Note the following guidelines for test day information on the CowCard:

- Up to 32 tests may be stored; if more than 32 tests occur, the latest data is overwritten.
- You can plot the items in the test day rows along a graph by using the PLOT command
- The items at the top of this tab are customizable. Right‑click on any item to add, change, or remove it.
- If your cowfile is connected to PULSE, the 305-Day Age Adjusted Milk (305AA) column is automatically added to this tab. This value is calculated from your test day data using the latest CDCB age-adjustment factors. See [What is 305AA and how does it differ from 305ME?](docId\:yA4ssE7qJIxfsLsTykxKY) to learn more.
