    Lectures

    The Designated Lecture Hours: Tuesday and Thursday 10:00 – 11:20 a.m. Although the lectures are
    asynchronous, these hours must be reserved by students for this course only because some synchronous
    activities, such as midterm tests, the welcome Zoom meeting, additional office hours and special
    sessions for FAQ’s, will be scheduled or announced on short notice in these time slots.

    Textbook

    The course package is available in the Laurier bookstore: B. Secord, S.J. Stack, D.C. Vaughan and T. Balfour: Logic and Algebra, 3rd Edition.

    Calculators

    No calculator is allowed on the midterm tests and the final examination.

    MyLearningSpace

    Materials related to this course and the full course outline will be posted on the MA121 MyLearningSpace website. You are responsible for checking here on a regular basis for important announcements.

    Evaluation

    A final mark out of 100 will be calculated as follows:


    • WeBWorK Assignments: 5%
    • Labs (tutorial and written quizzes): 20%
    • Midterm Tests (20% of the higher mark + 10% of the lower): 30%
    • Test 1 - Thursday, Oct 22, 10:00 – 11:20 a.m. (class time)
    • Test 2 - Thursday, Nov 19, 10:00 – 11:20 a.m. (class time)
    • Final Examination (2.5 hours; exact date, time and location to be announced): 45%

    The midterm grading policy is designed to accommodate slower learning pattern or accidentally
    abnormal performance, and encourage progress. Due to the accumulative nature of the learning
    outcomes of this course, an alternative grading scheme that replaces the sum of the midterm tests and
    final exam percentages by a 75% final exam may be applied at the end to encourage substantial
    progress .
    Students must earn at least 40% on the final exam to be eligible to pass the course.
    The final mark will be converted to a letter grade in accordance with the conversion table of the
    2020/2021 Undergraduate Calendar
