The burden of proof of both long and short term mastery of skills or concepts lies with the students. Mastery is demonstrated by significant achievement on tests, exams, and homeworks and quizzes.
Linked here is the Middlesex Colleges Grading Policy.
This is not the traditional 4.0 grading scheme used at most colleges.
With this grading scheme, a student earns credit for failing a test so the highest grade is not a 4.0 for an A but a 5.0 for an A. The mathematical and general definitions of each grade are listed below.
MCC Canvas Grades
Canvas is , however, a traditional grading system. Canvas computation does not work for this course but the grades must be posted in canvas. 
Students having disabilities who choose to disclose the disability must obtain official college recognition of the disability in order for the teacher to make any accommodation.
If a test, assignment, or exam is not completed at the instructorscheduled time, the grade of NG with the equivalent of ZERO (on a 0 to 5 scale) is assigned. THERE ARE NO MAKEUP TESTS, QUIZZES, ASSIGNMENTS. THERE IS NO EXTRA CREDIT.
If the instructor believes a student has cheated, copied, permitted another student to copy work, or participated in any unauthorized collaboration, the grade of CH with the equivalent value of TWO ZERO GRADES will be assigned & the scale below is modified to include one additional grade. Grades other than the final exam are sometimes curved by the instructor.

This page permits a student to determine "WHAT YOU NEED" in order to end the semester with a desired grade. EACH STUDENT IS REQUIRED TO TAKE THE FINAL EXAM, even if a negative "needed" points is determined below.
