MAT 127: Calculus C

Stony Brook            Fall 2010



All grades (not letter) should now be available on Blackboard; the letter grades should be available in solar. Your letter grade for the semester is completely determined by your Weighted Total 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 AA-B+ BB- C+C DF
weighted total 81+77.6-80.9 72-77.568-71.9 63-67.956-62.9 49-55.935.5-48.9 35.4-
These overall letter-grade breakdowns are based on the following letter-grade breakdowns for the five components of the weighted total:
   out of  A/A- C+/CDF
EE  2018+16-17 13-1510-129-
MI  10080+65-79 55-6441-5440-
MII  10075+57-74 45-5630-44 29-
FE  15011390-119 68-8948-6747-
HW (%)  10075+64-74.9 44-63.934-43.933.9-
The HW break-downs take into account the presence of the harder letter and end-of-chapter problems. The four highest grades on the final were 157, 149, 147, and 147 (out of 150).

In the unlikely case that your FE and WT scores meet the condition for one-step increase in the letter grade, you should have received an e-mail stating so (and this should be reflected in the letter grade posted in solar). If you have any questions about the final exam and/or the computation of your letter grade, please stop by your instructor's office hours in February. 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 3-111/121. If you believe your letter grade was computed incorrectly, please bring a print-out 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.

The HW grades shown on Blackboard are renormalized as if they were out of 100. Your grade there should be the sum of your WebAssign and written portion scores, divided by the maximum possible score (not including the bonus), and multiplied by 100. The maximum possible scores for all homeworks are shown below. If any of your grades is entered incorrectly, please let your instructor know.

MLC/RTC: 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

  1. 8 weekly non-MLC hours of the current MAT 127 teaching staff (see p2 here);
  2. 7 weekly MLC hours of the current MAT 127 teaching staff (see p2 here);
  3. MLC hours of other faculty (including Sam Grushevsky, Raanan Schul, Jason Starr; see the MLC schedule);
  4. MLC hours of TAs who recently taught MAT 127/132 (including Anant Atyam, Ben Balsam, Caner Koca, Raquel Perales, Chaya Rosen, Jun Wen, Xin Zhang, Zheng Zhang; see the MLC schedule).

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 also 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.

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, Teaching Staff, 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).
