I NEED ADVICE

Hi guys! I'm Paula. I'm having a hard time sorting my mind out on what to do in the future. I am currently a third year student taking up Bachelor of Science in Industrial Engineering. Back in High school, I don't see my life as far as anyone does. I was living my life everyday by just going to the flow on what the day will give me. I lived my life focusing on what will happen today than what will happen tomorrow. I graduated in High school without a plan on what to take in college and let my dad decide about it. He asked me "What do you want to be in the future?". I had a deep thought and i just said, "I just want to make lots of money to provide my needs and support my family in the future" - i knw Im immature. Dad said that if i graduate on any course, I will be able to work and earn money. Dad then told me that in the company where he works are dominated by industrial engineers and they earn as much as he does and if i want to earn a lot i should take it, so i did. Our school offers minor subjects that is not that related to our field and I find some subjects interesting and where i excel on it. This subjects are math and programming. On my second year in college, I had major subjects, subjects that are focusing on my course, and some minor subjects. I know that every major subjects are hard even in different fields but I feel that Industrial Engineering is really not for me, that i never belonged there in the first place, and i should have took IT as my course instead since I love logic and programming. I talked to my dad on what i really want because it is the first time that I felt being attached on something. Unlike Industrial Engineering that since first semester, i never once liked it. Dad told me that I have gone far already. He was against that I will shift to another course so i continued taking Industrial Engineering. This semester, my major subjects seems like an alien language to me, the feeling of you are listening and trying to understand it but it really won't sink into you mind what the lesson is all about. During activities, I find it hard to do the assigned tasks since i don't understand it. The feeling that you are doing something you don't really know. I really feel screwed and do regret taking this course but what can I do, my dad wants me to finish it and my sister is pressuring me too. I also find something that got my interest, I've been tutoring kids, being catechists, tutoring high school students in various subjects and I find teaching really interesting too.

What should i do now? continue this course or fight for what i want?
