Attendance/Absence Policies : Disciplined attendance is strongly encouraged. A student missing a total equivalent of two weeks of class work will be dropped. School policy requires dropping students with poor attendance. Poor attendance will severely impact your classroom performance.
Grading policy/scale: The grading for the course will be as follows:
A 90-100 %
B 80-89
C
D
F
70-79
60-69
<60
TESTS 90 %
HOMEWORK 10%
You must notify in advance if you cannot make class on test day. The test must then be taken on the next class day. Only one late test will be allowed.
