Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
Assigned later
Reference books, course materials, etc.
Handouts are given out at the class
Evaluation methods and criteria
Evaluated by problem solving and written examination at the end of the course.
