First • Keys will be posted. 12 One-Minute Paper • Submit by e-mail two 1-min papers within 24 h after lectures in nth week of the semester (n: last digit of your student number). • Putting the course content in your own words allows you to identify what you did and what you did not understand. • Chance to ask questions that arise while reviewing the day’s notes. • Do not submit a table of contents. Explain what you think was most important in the lecture, what you did not understand, and/or what you would like to know more about (if there is such a topic). Several lines at most. • Each 1-minute paper submitted per e-mail within 1 day of a lecture will earn you 5 points. 13 The first 1-min paper is due tomorrow at 1:00 PM!

Typically scores above 85% will correspond to at least an A–, above 70% at least a B–, and above 60% at least a C. 16 Regrades: If you disagree with your grade on any exam or assignment please provide me with the specific reason that you think your grade should be adjusted in writing. in Note that regrades will only be given for tests or exams completed in ink. in 17 Make-up Tests: No make-up tests will be given in this course. Each student will be permitted to drop the grade of their lowest scoring midterm. If a student misses a midterm for any reason, this will count as their dropped midterm. Absence from two or more tests in this course will result in a failing grade in this course (i.e., F). Similarly, absence from the final exam will result in a failing grade. final 18 Academic Integrity: Academic integrity is essential to a positive teaching Academic and learning environment. All students enrolled in University courses are expected to complete coursework responsibilities with fairness and honesty. Failure to do so by seeking unfair advantage over others or misrepresenting someone else’s work as your own will result in disciplinary action. The University Student Conduct Code defines scholastic dishonesty as follows: scholastic Scholastic Dishonesty: Submission of false records of academic achievement; cheating on assignments or examinations; plagiarizing; altering, forging, or misusing a University academic record; taking, acquiring, or using test materials without faculty permission; acting alone or in cooperation with another to falsify records or to obtain dishonestly grades, honors, awards, or professional endorsement. grades, Within this course, a student responsible for scholastic dishonesty can be Within assigned a penalty up to and including an "F" or "N" for the course.
