I am so dumfounded when our instructor in physics notify that we will be having a bonus exam (may ganoon ba?) right then. Bonus exam in the sense that it will be a bonus for us and the points will be added in our total score (don't know how to that). He have all the right namanto announce exams anytime but at this point, I do not have any calculator to use! And my memory screwed up! Good thimg may papel and ballpen ako, hahaha =P. Hindi pa naman ako nakapag - review. Tsk.tsk. Bad talaga.
