2. Grading Information

Exams

There will be three evening exams during the semester, E1, E2, E3.

There will also be a final, E4. The final will be comprehensive, but will be weighted towards material covered after the third midterm.

Exam Date Location Time Solutions
E1 Tuesday, February 3 Check here on exam day. 6:30 - 8:30 PM Available day after exam
E2 Tuesday, March 3 Check here on exam day. 6:30 - 8:30 PM Available day after exam
E3 Tuesday, April 7 Check here on exam day. 6:30 - 8:30 PM Available day after exam
E4 Friday, May 1 Check here on exam day. 10:30 AM - 12:30 PM Available day after exam


All of the exams will feature a mixture of multiple-choice and free-response questions. There will be partial credit available on the free-response questions, but not on the multiple choice questions.

The three evening exams, E1, E2, E3 and the final exam E4 will each be scored out of 100 points and will be combined to form the exam portion of your grade (also out of 100 points) by the following formula:

E = (E1 + E2 + E3 + 2*E4 - min(E1, E2, E3, E4))/4
In other words, your final exam score will replace your lowest midterm exam score, unless your final is lower than all of your midterms. If this were the case, then all four exams would be weighted equally.

Quizzes

Each meeting of the rectiation sections include a short quiz. Each quiz will consist of problems of a nature similar to the suggested homework problems assigned. The first quiz will occur in your first recitation section on January 15 and will cover the material from Sections 6.1 and 6.3 of the text (including using trig functions - see Sections 8.1-8.3). Subsequent quizzes will cover material from lecture subsequent to that covered on the last quiz and including that covered on the Wednesday before the recitation section.

There will be a total of 14 quizzes over the course of the semester. Your 10 best quiz scores will be averaged together and then scaled to give a score out of 100 points. This score will form the quiz portion of your grade, Q. Note that there is no way to make up a missed quiz - you will receive a 0 for any quiz that you miss.

Homework

Aside from the first week of class and Spring Break, homework will be due weekly. It is due every Thursday at 11:00 PM, starting January 22.

Homework due on Thursday will cover the same range of material as the quizzes from the same day. There is no way to make up homework or to turn it in late.

Homework is done through Webwork and is accessible through the following link:

Webwork (Your Student ID will serve as your initial login and password.)

The homework portion of your final grade, HW, will be calculated by equally weighting all 13 of your homework assignments for the semester, taking the average of the 12 best scores among these, and scaling this average to be out of 100 points.

Computing Your Grade

Your Exam, Quiz, and Homework grades will be combined into a final score, S, for the class according to the following formula:

S = 0.70*E + 0.15*Q + 0.15*HW

This score S will be translated into a letter grade of A, B, C, D, or F in a manner that is not stricter than the following table. While there is a chance that additional curving might cause the thresholds to be moved lower, it would be unwise to depend on this happening. Also note that 30% of your grade will come from Homework and Quizzes. These points should be relatively straightforward to accumulate.

Numerical Range Letter Grade
[88,100] A
[75,88) B
[60,75) C
[50,60) D
[0,50) F



3. Exam Policy: Cheat sheets, Calculators


A small (4" x 6") index card may be used as a "cheat sheet" for the evening exams and the final exam. You may write on both sides and include any information you deem useful.

Graphing calculators and programmable calculators are not permitted for this course.

Note: Use of a prohibited calculator at an exam is an academic integrity violation. Any detected violation of academic integrity will be referred to the disciplinary committee of the College of Arts and Sciences.



4. General Calculus Exam Policy: Date of Final, Excused Absences

The Mathematics Department has the following policy in place for the standard calculus sections, which includes this course:

The exam dates including the final were set by the College office before you registered for this class. You are therefore expected to take the exams at their scheduled times. If you are away because of a university sporting event or field trip, then you may arrange for your coach or professor to administer the exam. Excused absences may be granted in the case of illness or bereavement. All excused absences must be granted by Blake Thornton.

The final exam date cannot be changed for reasons of traveling convenience.


5. Text

Calculus and Its Applications, Eleventh Edition, Goldstein, Lay, Schneider, and Asmar

No other texts are required for this class.

6. Tentative Schedule

I will attempt to keep to the following schedule and hope not to deviate it from it by more than one day at any point in the semester. I have also included my current projection as to the material to be covered in each midterm. As with the rest of the schedule, this too is subject to change.

The Suggested Problems listed are not to be turned in - they are meant to give you a list of problems to practice on. I highly recommend that you work through them until you feel completely comfortable with the material in the given section. I also would recommend doing additional problems not on the list here. These problems are meant to be a starting point and are not meant to be exhaustive.

7. Additional Resources


 There are a number of additional resources available to you to help you succeed in this course. You are encouraged to seek out either Tim or me with your question during our office hours. If these times are not convenient for you, please email as we can sometimes make arrangements to meet at other times.

In addition, there are a number of other sources of help:

The Calculus Help Room

The Calculus Help Room is essentially staffed all day, M-Th and for three hours on Friday. The exact hours may be found here: Calculus Help Room Schedule

The exact location of the help room is not determined yet. It will most likely be somewhere in Lopata Hall. I will announce when a location has been decided upon.

Please see this page for a summary of the additional help resources available.
