Guidelines for
CHEMISTRY B
Box Elder High School
Grading: All scores will be totaled for each student.
The student's total will be divided by the total points possible to determine a percentage.
The percentage will be used to find a grade according to the following scale:
A's 100-95% A C's 79.9-76% C+
94.9-91% A- 75.9-71% C
70.9-65% C-

83.9-80% B- 59.9-55% D
54.9-50% D-
Below 50% F
Approximately 40% of the total points will come from the packet scores. About 35% of the total points will come from tests, and about 10% of the total points will come from daily participation quizzes. 20% will be given for a Project.
Daily Participation Quizzes:
Students will pick up quiz paper at the front desk when entering the room and answer the questions from the overhead projector. Quiz Papers will be put away at the tardy bell. The daily quiz is worth 5 points for doing it and 1 point extra credit if it is answered correctly.
These cannot be made up!!There is no other extra credit!!!
Attendance Statement:
1. Students are expected to be in class every school day.
2. One or two absences will not hurt your grade, but be careful not to accumulate too many.

0-1 tardies COULD earn Honors (H).
