Math 41 Autumn 2013

Home Schedule Section Assignments Office Hours Homework Exams

Exam Policies

All exams for Math 41 are closed-book, closed-notes, with no calculators or other electronic aids permitted. Each midterm counts approximately 26% toward your final grade, and the final exam counts approximately 38%. (Your overall exam average is the sum of all points earned on all exams, divided by the total possible points; this average counts 90% toward the final grade. No scaling or curving is applied to individual exam scores.)

If you have a course-related or competition-related schedule conflict with a midterm exam, you must contact your instructor at least a week in advance of the exam to make arrangements for an alternate (early) sitting; the same policy holds for OAE accomodations. No other schedule conflicts are accommodated for midterms, and alternate exam times are limited. The date and time of the final exam are set by the University; all students must take the exam at this time.

Pre-exam Advice and Information

  • Read Jessica Purcell's Tips for Success in Undergraduate Math Courses for good advice about how to study for a math exam.
  • Look at the homework and solutions -- and remember the answers to odd-numbered problems in the back of the book.
  • See below for practice exams. In addition, this course is cumulative, so you should go over the solutions to any exams already held this quarter in preparation for the next one.
  • We highly recommend the Concept Check, True-False Quiz, and Review Exercises at the end of each chapter. The solutions to all of these Chapter Review problems are posted here.

Specific Info on Final Exam: Monday Dec. 9, 7-10pm, Cubberley Auditorium

  • The exam is cumulative, covering all course topics with a much heavier emphasis on the material covered since Exam 2.

Practice Exam Questions

The following exam questions were used in previous incarnations of Math 41. Material covered for a given midterm in these classes does not necessarily correlate exactly to the material covered in Math 41 this quarter, so bear this in mind when working these examples.

Warning: Do not look at or print out the solutions to the practice problems below until after working on them yourself, taking some time, and going back later to try any problems you couldn't do the first time again. Doing the problems while looking at the answers renders them almost completely useless as preparation for taking an exam. Remember that the teaching staff are available to ask questions of regarding any of the review material.

Course Exams and Statistics

After each exam this quarter, you will be able to find solutions here, as well as information on the coursewide distribution of scores.

Exam 1: Tuesday, October 15, 2013, 7:30-9:30pm     Solutions     Grade Distribution

The top quarter of the class scored 72 (out of 88) or better, the median score was 64, and the bottom quarter of the class scored 53 or below (out of 88). The mean score was 62.1 points out of 88, with a standard deviation of 12.7 points. (See the histogram linked above for a more detailed view of where your score stands.)

Although letter grades are not given for individual exams, if the final grade were to be based on this exam alone, the B/A cutoff would be at approximately 69/70 points (out of 88), the C/B cutoff would be at approximately 56/57 points, and the lowest C-minus would be approximately 46 out of 88.

Exam 2: Tuesday, November 5, 2013, 8-10pm     Solutions     Grade Distribution

The top quarter of the class scored 69 (out of 88) or better, the median score was 58, and the bottom quarter of the class scored 48 (out of 88) or below. The mean score was 58.0 points out of 88, with a standard deviation of 13.7 points. (See the histogram linked above for a more detailed view of where your score stands.)

Although letter grades are not given for individual exams, if the final grade were to be based on this exam alone, the B/A cutoff would be at approximately 66/67 points (out of 88), the C/B cutoff would be at approximately 50/51 points, and the lowest C-minus would be approximately 40 out of 88.

Notes on your current cumulative standing:     Cumulative Exam Grade Distribution

Click on the link above to see a distribution of the sum of your Exam 1 and Exam 2 scores. The top quarter of the class has a total of 140 (out of 176) or above, the median total is 122, and the bottom quarter of the class has a total below 103 (out of 176).

If the final grade were to be based on the total of the midterm exams alone, the B/A cutoff would be at approximately 135/136 points, the C/B cutoff would be at approximately 107/108 points, and the lowest C-minus would be approximately 87 out of 176.

Final Exam: Monday, December 9, 2013, 7-10pm, Cubberley Auditorium     Solutions     Grade Distribution

The grades for your final exam are posted on CourseWork. The top quarter of the class scored 104 points (out of 132) or above, the median score was 90 points, and the bottom quarter of the class scored below 75 points. The mean score was 87.8 points out of 132, with a standard deviation of 21.6 points.
