Hi, Patrick.
First, you need to go to the MSDN website at:
http://msdn.microsoft.com/
Then you will need to click the link in the upper right corner for MSDN subscriptions. You will need to log into your subscription using the credentials given to you by your school/employer (you did not specify).
Click on My Account and select your active (non-expired) MSDN subscription in the dropdown menu.
On the right side, scroll down to Microsoft E-Learning and click the link reading
Get Code.
There you can enroll in the training.
Good luck!
Best wishes, Davin Mickelson
