The exam has a couple of case studies and questions could be from any sections from skills measured in the exam.
When I wrote the exam, the exam started with 2 case studies each with 6 questions and a mix of 43 questions. The questions types are of different types: drag drop, screen capture, PowerShell cmdlets etc.
The CBT Nuggets for SharePoint 2013 for 70-331 vce is an excellent resource and give a good heads up about exam. It comes with a couple of sections the author gives an exam alert. These hints give useful and extremely for real life SharePoint administration which I have implemented in our company as well. It would be beneficial as the CBT nuggets might not help you alone. This is my honest opinion. Please look for sample questions over Internet so that you are armed with type of questions.
