Evaluation method and criteria

Evaluation will be based on quizzes and a final exam.
(Final exam total: 80 points) + (quizzes: 20 points) = A total of 60 points or more (100 points) is required to pass.
Quizzes will be administered at irregular intervals during the lectures, 3 to 5 times a semester.
For the final exam, students will receive a 60% pass mark if they can reliably solve example problems from class and explain 60% of the items listed in the achievement goals.
For the final exam, students will receive an 80% pass mark if they can reliably solve end-of-chapter problems from the textbook and explain 80% of the items listed in the achievement goals.
For the final exam, students will receive a 100% pass mark if they can reliably solve end-of-chapter problems from the textbook and explain 100% of the items listed in the achievement goals.
