Instructions

1. The value of this test is 15% of the semester and the duration is 75 minutes.
2. Handouts for revision are already posted on LEA
3. An average of 7 to 8 questions is generally asked.
4. The test includes multiple choices questions worth a maximum of 20% of the test value.
5. In order to receive full credit for your answer, your work must be shown.
6. 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
