This final exam for the Business Lab Challenge course serves two purposes. First, it tests your ability to apply what you’ve learned in your first year of core classes to the case about the company Dropbox. Your capability to analyze and answer specific questions about the case is worth 30 of the total 60 points for the exam. You will need to open and read the case carefully and respond to the questions posed in the first part. In the second part of the case, you are given additional questions to address, along with an Excel template to download, analyze, and make recommendations to the Dropbox Finance team in the form of a short essay (3-4 paragraphs).  Second, this final exam is a calibration for the core subjects that will be tested in the Competency Exam on April 30th. There are approximately 25-50 questions in the pool for each of the ten core classes you completed in your first year. As this part of the exam is worth 30 points, you will draw only one question (T/F, multiple choice, short answer) from most core subjects, with a more extensive set of questions drawn from the Business Lab Challenge topics. We will use the distribution of your answers to calibrate the Competency Exam, which will be held on April 30th. Virtually all core subjects are simplified in this exam format – the questions are designed to test your conceptual understanding and fundamental principles of each class, not to replicate finals you have or will take for each subject area.  However, as both exams are closed book/notes and have restricted access through Honorlock or a Lockdown Browser, you should brush up on the key principles of each course and possess strong foundational knowledge, which every MBA must know.  For the questions specific to the Business Lab Challenge, you should review lecture materials and brush up on the resource library posted on One Drive, as there are questions specific to frameworks and the types of tools available in this course. Also included are foundational questions about project management, principles of good project consulting, and the Pyramid Principle/MECE. Questions in the pool draw upon the entire Business Lab Challenge experience.  A final note: this final exam is a take-home exam open for 24 hours only. Once you start the exam, you must finish it in one sitting, or your session will be flagged. Copy/Paste operations are disallowed within the exam.  Good luck, and get after it!
