(1) passed all long exams(2) has an average recitation score of 80% or better(2) has an average long exam score of 80% or betterAn exempted students final exam grade will be the average of the long exams
3. Please bring an ID during every exam. NO ID NO EXAM 4. If a student misses an exam or recitation for whatever reason, his grade is zero for that requirement. NO MAKE UPS are given. 5. A grade of 4.0 means conditional and that you will have to take the removal exam within a year. Completion period is within one year.6.
