Prerequisite

Lectures

You are strongly suggested to attend the lectures. No talking, food, or drinking is allowed in class. Please shut off your cell phone or switch it to "silent". Information about materials covered and homework assigned each lecture will be updated on the course website.

Homework

You will have graded homework turned in every Thursday at the beginning of Thursday's lecture. Late homework will not be accepted! The homework collected is to be considered a bare minimum of homework that you should do. "A" students will generally do nearly every problem in the exercise sections.
Put the following information at the top left corner of each page of your homework: full name, student ID, and the due dates. Your turned in homework will be graded on several factors including accuracy and neatness. It is your responsibility to make sure the grader can understand your work.
Homework is graded according to the following distribution. Total score of a homework is 20. 4 out of 20 is graded according to the amount of work being completed. And the remaining 16 out of 20 is graded according to the accuracy. We will choose to grade 4 problems in each assignment, and each problem counts 4 points.

Exams

Exams will consist of a number of multiple choice questions, whose answers you will mark on an answer card for reading by a scanning machine. A portion of each evening exam will consist of a free-response, lovingly hand-graded question, for which partial credit will be given. It is considered your responsibility to make your work clear and legible. If the grader is unable to easily find your answer and understand your work, you will miss points. (The final exam will consist entirely of multiple choice questions.
Exam rooms will be assigned before each test. You can look up your room at Exam seat lookup .
Exam Materials You should bring the following equipment to each exam:

Please do not bring the following with you to your exam:

After the multiple choice portion of the exam has been graded (usually the next day), there will be a limited period of time during which you can look at the papers in the Math office to raise questions about mismarked cards and similar issues. After this holding period your exams will be returned to you (possibly in the hallway in Cupples I). The day after the exam (usually between noon and 4 PM), scores for the multiple choice portion of the exam can be found here: Exam Scores Exam grades (with the handgraded grades) can be looked up on Telesis .

Grading scale

Homework: 20%, Mid1: 20%, Mid2: 20%, Mid3: 20%, Final: 20%. The grades are assigned according the percentage you are in the class.
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 Professor Shapiro. The final exam date cannot be changed for reasons of traveling convenience.
Letter grades will be given based on your overall score. The cutoffs for the various letter grades will be no higher than the following:

In total, we will collect 10 homework. You are allowed to drop one lowest homework score.
The score of the final test can be used to replace the lowest midterm exam score.

Calculator

You are NOT allowed to use a graphing calculator on the exams. You will be allowed to use a scientific calculator, (for example, a TI30X, generally available for $13 or less). Be sure the calculator you choose can handle logarithmic, exponential, and trigonometric calculations. It would be wise to use this calculator when you work your homework problems so you will be comfortable with it when you take the exams.
