In the OCP study guide you write under Study Tips > Taking advantage of context clues:
...you can assume a question’ s code block will compile and run if “Does not compile” and “Throw an exception at runtime” are not available in the list of answers.
However, the available answers in the OCA/OCP Practice Tests book's, chapter 3, question 16 and question 38, both include "None of the above", and neither "Does not compile" nor "Throw an exception at runtime", while the explanation for "None of the above" being the correct answer (in both questions), is that the code does not compile.
Is it possible to get a "None of the above" when there is a compilation error in the exam? If yes, may I suggest that you reformulate the Study Tips in future revisions of the book?
