Grades

Grade = 0.25*(HWI+TestI+HWII+TestII), where

• HWI = homework average for Chapters 1-2
• TestI = test grade over Chapters 1-2, Oct 13
• HWII = homework average for Chapters 3+
• TestII = test grade over Chapters 3+, Dec 8

• Homeworks
  • selected problems from homework will be graded.
  • homeworks are individual, not group, projects. Please don't turn in copies of other students' homework, or use rogue websites like Chegg or Slader
  • homeworks can be PDF, JPG or Word files (as few files as possible!).
  • late homework not accepted
• Tests
  • on-line tests on Blackboard
