Unformatted text preview: 1 Practice Final Exam C - FULL LENGTH The following practice exam contains questions from past final exams as well as new questions. You will get the most out of this practice test if you complete it under EXAM CONDITIONS - that is, without distractions and within a 2.5 hour time limit. It is not possible to match the actual exam length exactly, but it is close. This test contains items that sample from the learning objectives in the course, but does not test everything. The difficulty level is also similar to the actual final exam.
