SAS Certification Prep Guide: Advanced Programming for SAS 9, Third Edition: 3 Review

Those contemplating purchasing SAS Certification Prep Guide: Advanced Programming for SAS 9 Third Edition in preparation for the exam should immediately dispel any notion that this text is a finely edited piece of work. One should anticipate spending additional time rereading, interpreting and testing text material that is not clearly or fully explained, void of examples or, in many cases, include syntax errors in the code, mismatched dataset pictures and occasional errors in the quiz questions/answers.
For example, a more obvious error occurs in Chapter 17 where the text describes how to specify a directive as format using DD-MMMYYYY as an example. However, the picture accompanying the explanation clearly shows a format output in DD-MMMYYY—only three characters for year. Sometime these errors are easy to identify and do not necessarily pose any great burden for the reader. On the other hand, the instances where sloppy editing make a difficult topic almost impossible to understand are infuriating, even more so once you realize the problem was not due to your ineptitude but an error in the text. This is especially true for chapters 13-24 where the incidence for errors dramatically increase. Furthermore, the last section, Chapter 19-24, ceases to use the example datasets provided online and used extensively in the first half of the book. This clear divergence in editing means that the reader must generate their own examples in order test and gain a clear understanding of the topics covered. Not to mention there is no explanation given as to why the book only includes 5 chapter quiz questions (as opposed to 10 each for Chapter 1-18) for the last section. This makes it difficult to clearly gauge ones comprehension of the material.
Fortunately, the first 12 chapters covering both PROC SQL and macros are the most clear, concise, methodical and well written of the entire book—obviously benefiting from the large volume of documentation available from SAS on these topics. The text’s early diligence in coverage here makes up for some of the aforementioned failings in the second half.
In the end, IR17;m thankful that SAS went to the trouble to put together this text as a comprehensive guide for the exam. In reality, there are no other texts that would serve as a replacement. Although far from perfect, the text at least outlines the material one can expect to encounter on the exam. The editing errors, in the very least, serve as a critical thinking tool: they force the reader to constantly question and test the techniques and explanation provided. This in itself achieves the purpose in which one would expect to receive from an exam prep guide.
