The evaluation system we created is working well in our campus. For the didactic portion, I assigned: 10% for attendance,quizzes and attitude grade 50% for long exams-minimum of 3 per module 40% for final exam For the laboratory portion, I assigned: 40% for lab book and a powerpoint presentation 60% for competencies -a one in one practical exam Final Grade is 60% taken from didactic grade 40% taken from Lab. grade Thanks for giving me an idea of how to give extra credits for those absent during exams or with failing grades.
