Most of the questions on tests will require calculation. Therefore I recommend you having calculator, pen/pencil, and blank sheets of paper for test. Questions would be posted and emailed to you on the test date.
The exams will cover the chapter materials (theory and application of quantitative technique) and the difficulty level for problems would be similar to the practice and assignment problems.
Date and timing of the tests are provided in your course schedule. Please make arrangements to take the tests when they are scheduled.
