Type of evaluation, repetition, calculation of grade, etc. |
Grade in this course is calculated numerically based on total points/percentages of the two tests although the instructor may raise or decrease it by one grade based on the active/inactive participation in classes or the level of the homework. 5 (excellent): 87 – 100 % 4 (good): 75 – 86 % 3 (satisfactory): 63 – 74 % 2 (pass): 51 – 62 % 1 (fail): 50 or less % Should a student accumulate a total of 50 or less percentages, an additional chance is given to him/her to meet the requirements. |
