Programming without background is not easy to learn, cyber security is even harder. I've got a friend who retained and retake 3 times his IT SEC modules before graduating from SIM UOW. Each retake are few months apart. Be prepared to memorize lots of code and syntax for programming related, theories & math calculation for IT Sec.
Other thing to take note, what do you want to be after you graduate? Web developer, software engineer, cybersecurity engineer etc? Usually recommended to be specialize in field and not both.
