PAK Flash Cards
The PAK Flash cards is meant to accompany the Condensed Summary. This is a reference tool containing concepts that shall definitely be solid in your brain. 
 
The best practice is to read the study manual, to familiarize oneself with the materials (once or twice). Then read the condensed summary and add your own notes as you go through the condensed summary. As you read the condensed summary a second a third time around, it shall take you less and less time to go through the entire syllabus. The read through of all the flash cards results in a lower time than reading the condensed summary.
 
One of the difficulties of the FSA level exams is to understand the entire syllabus and remember it. The flash cards help in training your brain to save (at least) the main points from the entire syllabus and be able to review in a short amount of time.
 
Bonus: PAK Condensed Summary
The PAK Condensed Summary is meant to fix knowledge and concepts grasped in the study manual. It is not meant to be a mere memorization guide. As you read the PAK Condensed Summary, try to see that the concepts flow superbly. Try to fill in the gaps. 
 
One might say that the Condensed Summary is a collection of list-items, but the hope is that you shall discuss or speak to yourself, the explanations that shall accompany the list-items. Remember, the examiner is drifting away from retrieval type questions.
 
Unless you have outstanding knowledge about the syllabus, you are expected to read the Condensed Summary after reviewing the Study Manual.
