Math 415, Differential Equations -- Syllabus

  • The two classes were curved together and all exams were graded together - the same question in all exams of both classes was graded by the same reader. I can't give different letter grades to people who got the same scores on the same exams. An explanation for the difference was perhaps that most 2:30 students left the 1st midterm early, while the 12:30 class worked hard to the last minute. Maybe other explanations are more accurate. But the exams just measure - definitely not absolutely but only approximately - what the students learnt in the class. We grade e.g. all Math 151 exams together, also when the instructors are different, and in our case the TA was different, so the policy is reasonable.

    list of: --hw, mid1, mid2, final
    average: 77, ---65, ---50, --111 (12:30 class)
    medians: 89, ---69, ---53, --124 (12:30 class)
    average: 64, ----51, --52, --103 (2:30 class)
    medians: 70, ---50, -51.5, -103.5 (2:30 class).

  • HW due Friday, on the week ending the previous Wednesday.
