Hi, Juan. It's good to know that at your early age, you are already eyeing and preparing for the future. Tuition fee differs depende sa law school. Syempre, kung sa mga sikat na private schools, mahal. you have to shell out at least P60,000 - 75,000 per sem. Wala pa dun yung books and other materials. Sa mid-range na private schools, nasa 35,000-50,000. State Universities charge lower. Pero wala sa school yan. Nasa estudyante yan. I am a product of a state university (hindi UP) but I passed the bar, take one with high marks.
After graduation from high school, hindi ka pwede mag-law agad. You have to take a pre-law course. Four years yun. Pwede naman kahit anong course, basta may enough units ng english and math na kakailanganing mo sa law school. I would suggest you take up legal management if you intend to pursue legal studies. Pwede din naman Communication Arts, Psychology, Human Resource Management, Accountancy (para CPA -lawyer ka). Pwede ding engineering (maraming akong kaklase sa law school na engineer. After sa four years mo na pre-law course, dun ka pa lang pwedeng magproceed sa law school. Another four years yun, kung walang bagsak at regular academic load ka every semester. After graduation from law school, you will review for the bar, then you will take the Bar exam. Pag pumasa ka, lawyer ka na.
Regarding public prosecutor, meron namang assigned sa provinces and cities. Sila ang nagpo-prosecute ng criminal cases para sa government. Do you want to be a public prosecutor?
Criminal law and civil laws are subjects in law school. Malawak yang dalawang yan. Ang criminal law ay hinahati usually sa dalawang semester. Ang civil law ay mas malawak kasi sakop nyan ang family relations, obligations and contracts, property, donation, ,succession (tungkol sa mana), at marami pang iba. Hindi natin kayang i-discuss yun lahat dito sa forum. Pag nag-enrol ka na sa law school, matutunan mong lahat yan.
Good luck. Aabangan ko ang pangalan mo sa resulta ng bar exams nine or ten years from now ha.
