  2. CS1033b Final exam (40%)Monday April 15, 2013Time: 2:00 pm - 4:00pmThames Hall Gym 2-hour ~150 questionsMultiple Choice, True or False Mostly memorization  • Bring: two soft pencils, a good eraser, your student card • Don’t bring: IPOD, hat, notes, electronic devices

  3. Practice Questions- Where are answers? • http://www.csd.uwo.ca/courses/CS1033/exam/

  4. NOTE: To be eligible to pass the course, a student must obtain: • a weighted average of at least 45% on the major assignment and final exams AND the weighted average of the assignment marks must be at least 45 %. Here’s how to calculate it: Note thatweighted average = (total of weighted marks / sum of weights) and  weighted mark = (weight * mark) For example, if you received 60% on the final exam (weighted at 40 % of your final mark) and 80% on the major assignment(weighted at 20% of your final mark), your weighted average would be ((60*.4)+(80*.2)) / (0.4+0.2) = (24+16) / 0.6 = 40/0.6 = 66% WHICH IS ABOVE THE REQUIRED 45% TO PASS. NOTE though, if you did not hand in the major project and received 50% on the final exam, your weighted mark would be 33% and you would NOT pass the course, even if your overall grade for your labs, assignments and final exam was greater than 50%
