Attendance Details:

Attendance Details

Should a student accumulate the equivalent of two weeks’ worth of unexcused absences, s/he will be administratively dropped from class. The following chart indicates two weeks’ worth of absences:

Fall 2021

TTh

4 absences

 Example:  In a TTh class, students will receive a warning notification via Blinn College student email after 2 days of unexcused absences and will be dropped after 4 days of unexcused absences. 

When a student is administratively withdrawn from a course, they receive notification from the college via their official Blinn College email account. If a student is dropped from a class prior to the “Q” date, they will receive a “Q” in the class. When the student is administratively dropped after the “Q” date, the student will receive an “F” as stated in current college policy. Students are able to access their student email account via myBLINN. A student’s Blinn College email address is of the form firstname.lastname##@buc.blinn.edu, where ## are the last 2 digits of their Blinn College ID.

This semester’s “Q” drop date is December 3rd, 2021.

Once the "Q" date has passed, grades earned will be recorded.

Makeup Policy

The final exam grade will replace the lowest test score (or missed test) if it is to the student's benefit.  The student will not be allowed to make up a quiz if he/she misses class unless it is an excused absence recognized by the institution (See "Attendance Policy"). 

To account for emergency situations, at least two MyMathLab homework grades will be dropped at the end of the semester.  In the event of an excused absence, it is the student's responsibility to meet with the instructor to make arrangements to take a make-up test prior to the planned absence.

Section Policies

Students must adhere to Blinn's established Zoom protocol including but not limited to: maintain a classroom like setting, wear appropriate attire, minimize distractions, and keep camera on during class.  Misconduct will subject to appropriate disciplinary action as prescribed by the College's incivility protocols and/or considered an unexcused absence.

Not adhering to Blinn College established Back2Blann procedures are matters of incivility will be subject to appropriate disciplinary action as prescribed by the College's incivility protocols.

All Ecampus Dropbox submissions must be submitted as PDF files to be graded.

Technology issues are not a reason to miss or extend deadlines.

Bonus points or additional opportunities to improve grade ARE NOT awarded.  Grades are earned by completion of assignments and exams by deadlines throughout the semester.

Proctored Exams

The Mathematics Department requires all courses to give proctored exams as part of the grading criteria.  In order to maintain high academic standards, the following assessments are required to be proctored:  Proctored Unit Exams
