6 Grading Information Grading Rationale Evaluation Methods: Each instructor has the flexibility to develop evaluative procedures within the following parameters. 1. Written exams must represent at least 60% of the course grade. 2. Final exam must represent at lest 20% of the course grade. 3. The Post Test is to be embedded in the final exam and must represent at least 10% of the course grade. 4. Other activities may represent at most 10% of the course grade. Grading Scale A 90% - 100% B 80% - 89% C 70% - 79% D 60% - 69% F Below 60 % EASTERN ARIZONA COLLEGE Elementary Algebra
