My advice is that you go for what you're good at - computer science. If you really like a subject, you should go for it. There is no guarantee that if you do the wishes of your parents, you will end up being successful in your career. We are now living in the digital age. Any course in computer technology will be in high demand in the future. Do not allow anybody to confuse you into doing a course of their chice. What you like is what really count.
