What age do students graduate in the Philippines?

Let's see... 1 to 3 years in pre-elementary (Nursery, Pre-school and Kindergarten), 6 years in elementary school, 4 years in high school, and 4 to 5 years in college, depending on the course. Other courses such as medicine and law would require more than 5 years of study in college--4 years pre-medicine or pre-law and 4 to 5 years medicine proper or law proper. A regular student (not studying medicine or law) would spend 14 to 15 years in school, on the average. Pre-elementary education is an advantage, but not required.
