• The value of this test is 15% of the semester and the duration is 75 minutes.
• Handouts for revision are already posted on LEA
• An average of 8 questions is expected.
• This evaluation might includes multiple choice questions worth up to 25% of the test value.
• In order to receive full credit for your answer, your work must be shown.
• Double check your numbers. If the number of digits is insufficient throughout the calculation, giving a result different from the expected one, it will be considered a mathematical error
