The CKAD exam, as you know, is hands on. This means that efficiency measure in the speed that you can perform the tasks, needs to be a high priority for you when preparing for the exam.
Secondly, because it's applied knowledge, you must act as a practitioner. This means that you must also be proficient in the tools and environment itself that you'll use during the exam.
The study guide is broken down into the applied knowledge learning track. Since the exam isn't about just academic knowledge, but executing the answer reasonably quickly (you only have two hours), repetition is the best strategy for proficiency.
