Diagramming

So for questions 1 and 2, you don't bother writing out the contrapositives in the diagram. How do we know when this is unnecessary as it is in these first two questions? I often spend a lot of time writing out these contrapositives every time I diagram when I could have saved almost 20-30 seconds not doing that.

The answer to this really depends on you. The goal of diagramming everything is to improve your ability to spot the logical intricacies within each question. Knowing how to diagram will help you break down complicated questions, and you'll likely get to the point that you don't need to diagram every question. However, that's completely up to you and the way you feel most comfortable attacking the exam. Diagramming can help tremendously with accuracy, and as with anything, your diagramming will get faster with practice.

Sorry that this isn't a cut and dried answer, but I hope it helps.
