- April 13: Here is a more precise interpretation of the clause that requires you to score at least 50% on the mid-term and final exam combined together. Lets say your mark on the midterm was x1 (out of 30) and let x2 be your mark on the final (out of 60). Then it is required that
20x1/30+ 30x2/60 >= 25

Please note that the weights of the midterm and the final exams toward your course grade are 20 and 30, respectively. - April 7: Assignment 3 solution posted on Avenue.
