Course Description: MAT 211, Calculus III, covers from the textbooks: 

Multivariable calculus: analytic geometry, scalar and vector products, partial differentiation, multiple integration, change of coordinates, gradient, optimization, line integrals, Green's theorem, elements of vector calculus.


Text: CLP-3 Multivariable Calculus and CLP-4 Vector Calculus, by Joel Feldman, Andrew Rechnitzer, Elyse Yeager, available online at


Objectives: After completing MAT 211 the student should be able to: 


Prerequisites: MAT 193 or equivalent with a grade of "C" or better.


Grades: Grades will be based on two zoom video meetings 15-minutes examinations (50% total), a comprehensive final examination (20%), and quizzes, homework, video and other assignments (30%) for the remainder.

The exact grading system for your section is the following:


An oral examination will consist in giving a definition or a statement for a notion or result studied in class, and explaining two homework problems from the homework assignments. A list of the possible definitions and statements is posted on Blackboard. A definition or a statement will be chosen by selecting a random number from 1 to the number of definitions and statements on the list. The homework problems will be selected by choosing randomly the lecture number, then a problem number from 1 to the total number of problems in the assignment corresponding to that lecture. For example, the definition/statement number 5 will refer to the fifth item on the list of possible definitions or statements on the list. The homework problem (1,13) will refer to problem 9 in Section 1.3 in CLP-1: this is the 13th problem in the homework assignment for Lecture 1.1. Each of the two oral exams will be graded on a 100 scale, then the sum of the scores is divided by 4 and denoted by E.


Homework will be due every week, the day before quiz days, and each homework is worth 10 points. Each week one of the problems from the homework due for that week will be selected and graded on a scale from 0 to 4. The remaining 6 points will be awarded for completeness of the homework assignment. Submitting solutions copied from the back of the book is not forbidden but strongly discouraged, since copying solutions will not prepare you for answering questions during the oral examinations. The average of all homework scores is denoted by H. Homework will be submitted as a pdf with your paper work on Gradescope. There is no need to match the pages with the problems when submitting the homework, see


Gradescope can be accessed from the link in Content in your Blackboard course, and you can practice submitting your work on Gradescope using the assignment called Submission practice, which will remain open throughout the semester. You might be asked to explain your work on a submitted problem. Failure to provide an explanation might result in a score of zero for the entire homework assignment.


15 minutes quizzes will be given in principle every week, and will be graded on a scale from 1 to 10. The average of the quizzes scores is denoted by Q. Each quiz will consist of one problem, similar but not necessarily identical to one of the homework problems assigned for that week.


There are also 10 points awarded for explaining one homework problem on video. This portion of the grade is denoted by V. Videos will be due the day before quiz days and will have to be uploaded on Flipgrid


The homework problems from which to choose one problem to explain on video will be announced in class.


The final exam, which will consist of fifteen problems similar to problems assigned as homework throughout the semester, will be graded out of a maximum possible 200, then the score is divided by 10 and denoted by F.


To determine your final grade, compute E+H+Q+V+F. The maximum is 100, and the grade will be given by the rule:

A: 93‑100; A‑: 90‑92; B+: 87‑89; B: 83‑86; B‑: 80‑82

C+: 77‑79; C: 73‑76; C‑: 70‑72; D+: 67‑69; D: 60‑66; F: Less than 60. You will be able to follow your progress in the class in Blackboard under Grade Center throughout the semester.
