## GRADING POLICY

### Final Score Determination

Your final score (100 points max) is the sum of the following:

- three exams: up to 25 points each, 75 points total
- 13 weekly HW assignments (weighted by your performance on follow-up quizzes): up to 5 points (As of February 8, the total number of HW assignments included in grading has become 12 because of WileyPLUS service interruptions for HW4.)
- 12 weekly discussion session quizzes: up to 20 points
- HITT-based quizzes: up to 5
**BONUS**points

### Exams

During the semester, there will be two mid-term and one final exams. Each exam will have 20 multiple choice problems (one point per problem; no penalty for wrong answers). Therefore, you can earn as many as 20 points on each exam. The earned exam score will be calculated using the following formula:

_{E}x

**25**,

where f_{E} = (number of correctly answered questions) / (number of problems on the exam, i.e. 20)

Therefore, each exam will count up to maximum **25 points** toward your final grade.

Should you have to miss any of the three exams for a **legitimate** and **documented** reason, **one and only one** make-up is possible.
The make-up will be offered at the end of the semester; it will be a cumulative exam based on the entire course material.

### Homework

The homework assignments are administered via the WileyPlus online system. You must purchase your personal WileyPlus access code and register at the WileyPlus website.

- The schedule of 13 weekly homework assignments is given at Course Schedule.

- You must click the
**Submit Answer**button for the system to record your response. The HW system will provide you with instant feedback on whether or not your answer is correct, and you will be permitted**five tries (until the due date/time)**to get the answer right, and receive credit. To be accepted, your answer should be**within ±2%**from the correct one. Do not round off numbers in the intermediate calculations to avoid the loss of the precision. Enter your final answer with at least three significant digits.

- The due date and time are on
**Tuesdays at 10:00 pm**unless otherwise noted on the Course Schedule. You will not be able to submit your homework past the deadline, regardless of the reason (participation in various events, sickness, computer system freeze, loss of internet connection, etc.). No make-ups for the missed homework assignments are possible.

- Your scores for the homework assignments will be weighted by your performance on the follow-up quizzes (which will be based on the homework problems):
[HW Weighted Score] = f

_{H}x f_{Q}where f

_{H}= (HW points) / (max HW points)

and f_{Q}= (Quiz points) / (max Quiz points)If f

_{Q}≥ 0.9, then we will take [HW Weighted Score] = 1. In other words, if you demonstrate mastery of the homework content by scoring in the top 10% of your quiz score, it doesn't matter what your homework score was that week, even if it was zero. But do keep in mind that to do well on the quizzes and the exams, you should understand how to solve the homework problems! - Some homework assignments do not have follow-up quizzes; for these assignment
[HW Weighted Score] = f
_{H}x 1

To provide some (10%) forgiveness for illnesses and other challenges that life may throw at you, this total score will be divided by 0.9 at the end of the semester.

**5**.

(The formula was revised, by dropping HW4 which was affected by WileyPLUS service interruptions. 02/08/17)

If the score exceeds 5, it will be truncated at 5.

Why do we weigh the homework by your performance on quiz ? We believe this scheme strongly motivates students to do homework assignments by giving them an explicit "money value", but, at the same time, discourages cheating on homework assignments by devaluing raw HW points, should one fail to confirm his/her understanding of the material at the time of a follow-up quizzes.

### Discussion section quizzes

During the discussion sections, you will be given 15-min quizzes with a problem very similar to one of those from the preceding HW assignments. Each quiz is graded on the 10-point scale, with a one-point step. The schedule of quizzes is given at Course Schedule.

To provide some (10%) forgiveness for illnesses and other challenges that life may throw at you, this total score will be divided by 0.9 at the end of the semester.

**20**.

If the score exceeds 20, it will be truncated at 20.

Make-ups for the missed quizzes are possible only if you have a **legitimate** and **documented** excuse. The decision on whether the excuse is acceptable will be made by your TA. Make-ups must be arranged with your TA no later than within **one week** after the missed quiz and the make-up quiz should be taken no later than within **three weeks** (unless there are very special circumstances). No make-ups will be allowed after that. No make-ups will be allowed during the last week of the course. Students can make up no more than 2 quizzes.

### HITT quick quizzes

During lectures, you will be given 1-2 minute quizzes that you should answer using your HITT remote control. The HITT quizzes will allow you to earn up to 5

**bonus**points. Each quiz is graded on the 2-point scale: 2 points for the right answer, 1 point for wrong answers, and 0 for no answer. Number of quizzes per lecture will vary; so will the time during lectures when quizzes are administered.

We will apply an overall 20% forgiveness for missed HITT quizzes. Your final HITT quiz score will be calculated as follows:

**5**.

If the score exceeds 5, it will be truncated at 5.

No make-ups for the missed HITT quizzes will be possible, regardless of the reason (participation in various events, sickness, forgotten or malfunctioning HITT remote control, etc.).

### Letter Grade

Total minimal scores (**out of 100 points**) ensuring a particular letter-grade are shown below.
None of the scores will be rounded.
The scale is *absolute* and will not be adjusted to a curve; hence, there is no competition between students.

Grade | Required score (out of 100) |

A | ≥ 85 |

A- | ≥ 80 |

B+ | ≥ 75 |

B | ≥ 70 |

B- | ≥ 65 |

C+ | ≥ 60 |

C | ≥ 55 |

C- | ≥ 50 |

D+ | ≥ 45 |

D | ≥ 40 |

D- | ≥ 35 |
