V. Grading

  1. Weekly Homework: 30% of Final Grade, 20% written submission to Gradescope, 10% PrairieLearn
    • Grading: Homework average is computed by dropping the two lowest scores and then computing the average; this implies that each student may omit two homeworks in case of extenuating circumstances. Since the solutions will be posted immediately after the submission deadline, no late submission will be accepted.
    • Submission: Homework should be uploaded as a PDF file to Gradescope in which we have added each student enrolled. If you have not been auto-enrolled to our course Gradescope, you may join using entry code 6ZGWJ6.
    • Due dates: Homework is assigned each Wednesday, due the following Wednesday at 11:59pm. The corresponding solution will be posted immediately after the due date.
    • Write neatly. Please box the equations you will be solving and the final answer. If we cannot read it we cannot grade it!
    • Regrade requests must be submitted on gradescope within one week of grades being posted. All regrade requests must have a brief justification.
    • PrairieLearn: www.prairielearn.org (sign in with Illinois; first time, enroll in course ECE 310). There is PrairieLearn weekly homework that is due at the same time with written homework (Wednesdays at 11:59pm).
    • Again, late homework submissions will not be accepted.
  2. Exams (will be held in-person): 70% of Final Grade

VI. Integrity

This course will operate under the following honor code: All exams and homework assignments are to be worked out independently without any aid from any person or device. Copying of other students' work is considered cheating and will not be permitted. By enrolling in this course and submitting exams and homework assignments for grading, each student implicitly accepts this honor code.
