Course Policies

1. Every student should attend classes regularly and punctually. If a student gets absent, he/she should present an excuse letter signed by the College Secretary, the Department Chairperson or the College Dean. 2. Students who incur absences in more than 20% of the class hours (equivalent to 8 sessions) may be dropped from the rolls and given a grade of “UD” or “5.0”, depending on his/her class standing. 3. Special tests/exams and/or exercises/activities may be given to a student who gets absent with a valid reason provided that he/she presents an excuse letter signed by the College Secretary, the Department Chairperson or the College Dean. 4. Assignments/homework and other requirements should be submitted on time. Late submission of assignments shall not be tolerated and will have corresponding deductions. 5. Honesty should be practiced at all times. A student who is caught cheating shall be given a grade of 5.0. 6. Pursuant to Section 16 of the IRR of RA 9710 also known as the “Magna Carta for Women”, the class shall observe equal access and non-discrimination to all students. It shall ensure that gender stereotypes and images in the educational materials shall be observed. Gender-sensitive languages shall be used at all times. 7. The students are required to undergo intensive review class in Mathematics and English which will be scheduled by the Department Chairman on the First Week of every semester subject to approval by the CEAT Dean and VPAA.
