Preparing for the Base SAS Certification Exam

I tried studying for the SAS exam using Anki decks, but I found that this wasn't a very effective way of learning the syntax.  So, I tried a different strategy: going through the SAS Certification book and writing code snippets related to each concept.  The certification test questions frequently want you to spot errors, so I have created snippets to illustrate frequent mistakes as well as correct code.  When possible, I used the datalines feature to make very small data sets (a few rows are usually enough to illustrate the concept).
