Hi, I'm Currently a 2nd Year Civil Engineering Student! Like you hirap din ako sa pag dedesisyon since papalit-palit ako ng gusto. Until now, i'm not really sure sa course ko -- although I'm currently doing just fine and happy. About sa usaping Matematika, Both CE and ECE will be Math Oriented kahit anong piliin mo, iba lang ng Focus. Parehas naman yan may Calculus 1 to 3, Data Analysis, Physics, Economics, Advanced Math (Numerical solutions na tawag ngayon eh), and etc. So like said, dun lang sa focus ng subject magkakaiba like kaming CE will take a much more in-depth Physics on Bodies since our field is about structures. ECE naman will have a more in-depth approach sa Phenomenon surrounding Electricity.
To answer yung iba mong mga Questions:
About sa Gastos, currently i'm enrolled in a State University so wala namang problema about Fees. Yung mga Supplies ko lang talaga need lalo na nung First Three Semesters sa, Drawing Materials. Pero around 1500 lang nman siguro nagastos ko dun. However, medyo ibang usapin yung Laptop since sobrang magagamit yung AutoCAD sa field namin, madami samin eh nag invest na dun, can't talk on behalf lang sa mga ECE.
Kung Demand naman ang pag-uusapan. Mas In-demand si ECE kaysa kay CE lalo na medyo in line si ECE sa IT Field.
Ngayon advise ko lang kung yan yung pinagpipilian mo. Punta ka dun sa may pinaka interest ka since I think you'd find it more enjoyable and interesting since your curiousity can actually help you with your studies. Kung di ka curious dun sa subject eh baka pwersahan mo lang matutunan.
