MAT 127: Calculus C
Stony Brook            Spring 2022 |
---|
Congratulations to those of you who did excellent job on the final exam, especially after a setback on the second midterm! The grades (not letter) should now be available on BlackBoard; the letter grades should be available in solar after Thursday evening. Your letter grade for the semester is completely determined by your WeiTot on Blackboard (but rounded to one decimal place) in accordance with the following table, with the minor exception described at the beginning of the semester.
letter grade | A | A- | B+ | B | B- | C+ | C | C- | D+ | D | F |
weighted total (%) | 78.5+ | 76-78.4 | 68-75.9 | 62-67.9 | 59.2-61.9 | 52-59.1 | 44.6-51.9 | 40-44.5 | 35-39.9 | 31-34.9 | 30.9- |
  |   out of  | A/A- | B± | C+/C | D | F | |
MI |   | 80 | 65+ | 50-64 | 40-49 | 28-39 | 27- |
MII |   | 80 | 60+ | 48-59 | 35-47 | 22-34 | 21- |
FE |   | 150 | 110+ | 85-109 | 60-84 | 45-59 | 45- |
HW (%) |   | 100 | 77+ | 60-76.9 | 50-59.9 | 33-49.9 | 32.9- |
In the unlikely case that your FE and WT scores meet the condition for one-step increase in the letter grade, you should receive an e-mail stating so before the office hours on Thursday (and this should be reflected in the letter grade posted in solar); if this does not happen, please contact your instructor. If you have any questions about the final exam and/or the computation of your letter grade, please stop by the office hours on Thursday. If you would like to review your final exam, please bring a copy of the solutions (unless you have an A for the semester); the exams may not be removed from Math 3-111. If you believe your letter grade was computed incorrectly, please bring a printout of all grades from BlackBoard along with your computation.
Please do not ask to increase your letter grade for any reason (including for making up some work). The same grading policy applies to everyone in the course, and it would be completely inappropriate to be otherwise. In any course, the grading policy is up to the (head) instructor to determine and is not subject to discussion. In this course, the implementation of the grading policy was more transparent than is normally the case (in how many other courses have you seen explanations of grading for individual exam questions?). However, this should not be construed as an invitation for questioning the grading policy itself; the grading policy for this course should have been clear to you at the beginning of the course, and if you did not like it then, you could have postponed taking MAT 127 for a semester or simply moved to MAT 132.

Due to the size of the class, it will not be possible for the lecturers and the graders to respond to every e-mail. Before sending an e-mail with an administrative question (e.g. about exam locations), please check to see if the answer to your question is contained in the course information handouts (General Course Information, Additional Course Information, FAQs, Office Hours, etc.) or on this website or is available through the Stony Brook University pages. You are highly unlikely to receive a response to such questions. Please do not e-mail mathematical questions (e.g. how to do a specific problem); instead please come to office hours. If you would like to discuss your homework grades (as opposed to the homework itself), please speak with the grader who graded it (see below).

Please generally attend the lecture you are registered for. If you are unable to attend a class in the lecture you are registered for or would like to see a specific topic again, you may attend another lecture. However, due to space limitations, the students registered in any given lecture and arriving on time will have priority. On the other hand, please free to attend any of the office hours.
Additional help is available through the Math Learning Center, which is located in Math S-240A and staffed by math grad students and faculty, as well as through the Residential Tutoring Centers. The morning hours at MLC are usually less popular and thus the staff are more likely to be able to devote more attention to each student. Some of the questions in MAT 127 are rather technical, and some MLC/RTC tutors may have difficulty helping you because they may not be certain what you already know (or should know). You are most likely to receive MAT 127 specific answers at the

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty are required to report any suspected instances of academic dishonesty to the Academic Judiciary. For more comprehensive information on academic integrity, including categories of academic dishonesty please refer to the academic judiciary website.
Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of University Community Standards any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn. Further information about most academic matters can be found in the Undergraduate Bulletin, the Undergraduate Class Schedule, and the Faculty-Employee Handbook.
