When you start a session for a student account that is unregistered, you’ll see a screen notifying you to that effect (Figure 16.1).

If you want to register the account, tap the Register button.

Figure 16.3 – Register mTrial Window

On the dotted line, write the eight-digit registration code you received by from Mobile Thinking. The registration code must be the one associated with the Student ID displayed on the second line of the window (in this example, Greg Olmstead). If you need a registration code, visit http://www.mobilethinking.com/dtm/purchase.htm and follow the instructions for purchasing a registration code for mTrial.

Tap Cancel to return the user to the screen from which you opened the Register mTrial window.

After entering the registration code, tap OK. If the registration code matches the Student ID, mTrial displays a Registration Complete message (Figure 16.4). If the registration code does not match the Student ID, mTrial displays an Invalid Code message (Figure 16.5).

In registered copies of mTrial, Register Program is removed from the Begin Visit screen (Figure 16.6) and there is no message indicating that mTrial is “Storing N of 10 Sessions” (Figure 16.7).
