CS232 - Software Engineering

Exam 2 Review

The midterm exam will be 50 minutes, closed book, closed note, and handwritten. Illegible (not clear enough to be read) answers will be subject to assumptions regarding the written content or in extreme cases, not graded at all. All answers should be concise reponses to the prompts. Excessively verbose responses that do not address the question directly will not receive full credit.

The following is a potential question pool for the exam. While the content of the questions will be conceptually derived from this list, wording and/or presentation may differ on the actual examination.

Format

13 Questions:

  • 1 applied UML class diagramming question
  • 6 written response questions
  • 1 multiple choice
  • 3 Fill-in the blank
  • 2 True/False
