ECE 313, University of Illinois at Urbana-Champaign

## ECE 313 Grading Scheme Spring 2022

### Grade Distribution Formula: Scores will be weighted as shown below to determine your total score, which in turn, will determine your grade.

The score formula is as follows (Homework score is the average of your highest 10 out of 13 scores):

• Score 1 = 15% Homework + 25% Midterm Exam 1 + 25% Midterm Exam 2 + 35% Final Exam
• Score 2 = 15% Homework + 15% Midterm Exam 1 + 30% Midterm Exam 2 + 40% Final Exam
• Score 3 = 15% Homework + 30% Midterm Exam 1 + 15% Midterm Exam 2 + 40% Final Exam
• Total score = Max{Score 1, Score 2, Score 3}

Letter Grades: After computing each student's total score we find the mean m and the standard deviation s of the total scores. Letter grades are assigned using cut-offs that are based roughly on a mixture of

• objective criteria (85% = A, 70% = B, 55% = C, etc.),

and

• statistical criteria (above-average scores = B or better, etc.).

As a rough guideline, we intend to award

• A's to scores greater than min(m+s,85)

• B's to scores in the range min(m,70) to min(m+s,85),

• C's to scores in the range min(m-s,55) to min(m,70)

• D's to scores in the range max(m-2s,45) to min(m-s,55)

• F's to scores below max(m-2s,45)

+ and - grades are typically awarded at the edges of the above cut-offs. The percentages of A's and B's awarded in ECE 313 are comparable to those awarded in 300-level required courses in the ECE Department.
