Methods of Evaluation of Competencies:

Evaluation of student mastery of course competencies will be accomplished using the following methods:

A minimum of four tests    60-70% of grade
Laboratory projects        30-40% of grade
                             100%
Grading Scale:
   90-100% = A
   80- 89% = B
   70- 79% = C
   60- 69% = D
    0- 59% = E

Caveats: NONE
