Grading

• Examinations
  • No make-up exams unless I approve of reasons prior to the exam
  • All exams account for 80% of your final grade
  • First exam accounts for 20% of your final grade
  • Second exam accounts for another 20% of your final grade
  • The final exam accounts for 40% of your final grade
  • All exams are open book and open notes, but no cheating is tolerated
  • All exams are, by default, multiple choice. However, I reserve the right to change the form of questions.
  • All exams have some ``extra credit'', see below
  • Letter grade equivalence: given $t_i$ is the total number of questions of exam $i$, $b_i$ is the baseline number of questionsof the same exam, and $r_i$ is the number of questions answered correctly:
    • F: $r_i < 0.1 \times b_i + 0.2 \times t_i$
    • D: not F and $r_i < 0.3 \times b_i + 0.2 \times t_i$
    • C: not D and $r_i < 0.5 \times b_i + 0.2 \times t_i$
    • B: not C and $r_i < 0,7 \times b_i + 0.2 \times t_i$
    • A: $r_i \ge 0.9 \times b_i + 0.2 \times t_i$
• Homework Assignments/Projects
  • All homework assignments/projects account for 20% of your final grade
  • +2% per day early
  • -20% per day late
  • I will use the last submission for grading
  • I reserve the right not to grade any submission that is not submitted according to specifications
  • Letter grade equivalence ($s_i$ is the adjusted score of a submission $i$ after early/late adjustments, $p_i$ is the number of points for the work):
    • F: $s_i < \frac{p_i}{8}$
    • D: not F and $s_i < \frac{3\times p_i}{8}$
    • C: not D and $s_i < \frac{5\times p_i}{8}$
    • B: not C and $s_i < \frac{7\times p_i}{8}$
    • A: $s_i \ge \frac{7\times p_i}{8}$
• Final grade
  • Weighted average of all exams and homework assignments/projects.
  • Letter grade is based on boundaries determined by weighted average of all exams and homework assignments
  • Want exact formulae, here they are:
    • let $R = 0.2 r_1 + 0.2 r_2 + 0.4 r_3$, where $r_1$, $r_2$ and $r_3$ are the number of correct answers of the first, second and final exams, respectively.
    • likewise, let $T = 0.2 t_1 + 0.2 t_2 + 0.4 t_3$ and $B = 0.2 b_1 + 0.2 b_2 + 0.4 b_4$, subscripts indicate exam number (1 means first, 2 means second and 3 means final)
    • Let $S$ be the sum of adjusted scores of all homework assignments and projects
    • Let $P$ be the sum of total points of all homework assignments and projects
    • F: $\frac{R}{B} + 0.2 \frac{S}{P} < \frac{0.1 B + 0.2 T}{B} + \frac{P}{8}$
    • D: not F and $\frac{R}{B} + 0.2 \frac{S}{P} < \frac{0.3 B + 0.2 T}{B} + \frac{3P}{8}$
    • C: not D and $\frac{R}{B} + 0.2 \frac{S}{P} < \frac{0.5 B + 0.2 T}{B} + \frac{5P}{8}$
    • B: not C and $\frac{R}{B} + 0.2 \frac{S}{P} < \frac{0.7 B + 0.2 T}{B} + \frac{7P}{8}$
    • A: $\frac{R}{B} + 0.2 \frac{S}{P} \ge \frac{0.7 B + 0.2 T}{B} + \frac{7P}{8}$
