1. The academic performance of students is evaluated using the grade point average (GPA) system. The following grades are used:

   Grade	Point	Significance
   A B+ B C+ C D+ D F	4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.0	Excellent - Good - Fair - Minimum Fail

   In some courses, such as Industrial Training, an S (satisfactory) or U (unsatisfactory) grade is given. These grades have no point values. Since these courses, though required, normally have no credits, they shall not be included in the calculation of the semester and cumulative grade point averages.

   The I grade may be temporarily given for courses where coursework has not been completed and it is not the student's fault. Issuance of this grade is very rare and must be based on circumstances that are beyond the control of the involved student. An I grade must be removed within 90 days after the semester ends.

   Course withdrawals after the first two weeks but still within the first ten weeks are given the W grade. No withdrawals are permitted after ten weeks of a regular semester, except under special circumstances.

2. A placement test of some courses can be substituted for a regular evaluation. A student whose placement test result is "Accredit" will earn the credits without studying such a course and his/her academic record will bear "ACC" which carries no grade point and will not be used in the calculation of the GPA.
3. A student may retake a course which he/she received a grade of D or D+. All the grades received in the same subject will be used for the calculation of the cumulative grade point average, but the credits will be earned only once.
4. An F grade will be counted as zero point and the course credits will be used for the calculation of both the semester and the cumulative grade point averages.
5. A compulsory course with either an F or a U grade must be re-taken until a passing grade is obtained.
6. A student may choose to re-take an elective course with either an F or a U grade or to take another course instead.
7. Only courses that are given at least a D grade or an S grade or "ACC" are counted towards earned credit accumulation.
8. In case a student is required to repeat a course or take another course as a substitute, the credit(s) of such a course will be accumulated only once.
9. A student who misses an examination due to an uncontrollable cause must immediately submit evidences stating the cause of his/her obstacle to the instructor and his/her advisor for initial consideration. If the matter is deemed adequately logical and approved by the instructor, the instructor and the advisor will submit the matter to obtain the director's approval for arranging an appropriate process such as a make-up examination. If the matter does not receive an approval, the mark for the missed examination will be "0".
10. The maximum time limit to complete a bachelor's degree is 7 years.

1. The institute will evaluate the status of each student based on his/her academic performance at the end of every semester. Each student must maintain a cumulative grade point average (CGPA) of at least 2.00, otherwise he/she will be issued a "warning 1", "warning 2", or "probation" status in the following semester, as appropriate.

6. If a student has completed all the courses required by the curriculum but his/her CGPA is below 2.00 but not less than 1.80, then he/she is allowed to continue taking courses for no more than 3 semesters (subject to a total time limit of 7 years for the entire enrollment) to improve the CGPA to 2.00.
