• 4) Extra Credit (EC): The following EC problems are worth 0.5 points each:
  Exercise 1.14, 1.15, 1.17, 1.18, 1.21, 1.22
  
  0.5 points are awarded when an EC problem has been solved entirely, i.e., all parts. It does not matter whether your answer is correct or not. You just get points for attempting to solve each problem part. Please turn in solutions to EC problems as part of your regular homework submission.
  
  Alternatively, you can attend one of the Recitation/Tutoring sessions next week and obtain a total of 3 EC points when you attend 50min out of the first 60min of a Recitation/Tutoring session next week when these problems will be solved during that session. Please be aware that 3 points is the maximum number of EC points you can obtain in each week. You will not obtain 6 points even if you turn in solutions to these EC problems as part of your regular homework and also attend one (or more) of the Recitation/Tutoring sessions next week.
