The MOAC Lab manual referenced here is for Server 2008 configuration. I have adapted the exercises to be run in the newer Server 2012 environment. I have included the questions from the lab manual, however, many of the questions may vary or not be relevant to Server 2012. I find this to be one of the more interesting aspects of identifying the differences.
Please feel free to follow along, consider the questions, and send any questions to me.
Installation of Server 2012
After step 1
Question 1: What drop-down boxes are available on the initial configuration screen?
After step 5
Question 2: Why is the Upgrade option disabled? (In Server 2012, the option is not disabled, but if clicked, an alert comes up. Why would it be impossible to perform an upgrade installation?)
Installing Windows Server 2012 Part 2
Configuring Windows Server
Configuring Server 2012

Question 3: What network components are installed on your computer?
Quicker installation of a second server.
Part B after step 7
Question 4: What is the current name of your computer?
Part C after step 2
Question 5: What is the current name of your computer?
Installing and configuring a Server Core computer
Part B after step 1
Question 6: What do you see when you log on to a Server Core computer?
If you have not yet done so, take a screenshot at this point. If you have time, you may run Windows Updates first. This will give you a base image to revert to if necessary.
