Exam Policies

All exams for Math 42 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 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.

There is a regrade process after each midterm exam to address possible grading issues on individual problems. Your original, unaltered exam must be accompanied by a cover letter clearly explaining why the particular problem merited more points, and it must be turned into your TA no more than two weeks after the official exam date. (Once submitted, any part of the exam may be regraded; please also note your exam may have been photocopied to ensure compliance with the Honor Code.) The submission deadlines are firm, and no exceptions will be made, so please arrange to pick up your exam paper from your TA in a timely manner. (For privacy reasons, we can only release your exam, whether in paper or electronic form, to you.)

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 Exam 1: Thursday Oct 16, 7:30-9:30pm, Room 320-105

  • The exam will cover all course material up to the lecture of Friday, October 10 (Stewart text sections 5.1-5.6, 5.9-5.10, 8.1-8.5, Appendix D pA30-A33).

Practice Exam Questions

The following exam questions were used in previous incarnations of Math 42. Material covered for a given midterm in these classes does not necessarily correlate exactly to the material covered in Math 42 this quarter, so bear this in mind when working these examples. (For instance, the topic of improper integrals appears on some years' first midterms, and on other years' second midterms.)

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.
