A problem set with approximately 1,000 questions, organized by field. This problem set corresponds to the Subject A examination of the Fundamental Information Technology Engineer Examination. Focusing on questions from past Fundamental Information Technology Engineer Examinations, primarily morning session questions, and considering recent trends, it includes approximately 1,000 questions, including those from the morning session of the Applied Information Technology Engineer Examination, organized by field. The units are structured with the same table of contents as the textbooks "IT World" and "IT Strategy and Management," allowing for cross-referencing during study. Repeatedly working through past questions is a highly effective and standard study method for preparing for the actual examination. This problem set can also be used for preparing for completion exams.
