When I started on the first
Java Exam Cram book in 1999, I realized that creating good sample questions was not all that simple. As I worked up questions for the book I made them available for comment on-line using an
applet that emulates the real
test environment. Thanks to many useful comments from users, I was able to get rid of ambiguous or incorrect questions. Furthermore, by collecting every set of answers I was able to determine the question topics that caused users the most trouble. I selected a total of 19 questions that seemed to cover most of the exam objective areas and put them in a separate "Hardest" collection.
Taking these questions has been one of the options at my certification resources page since December 1999. There have been slight improvements in the questions as users have raised concerns (thanks folks!) I recently analyzed the collected results from over 65,000 individual tests, resulting in the statistics
shown here in case you are interested. Bill
