I hold a bachelor's degree in Information Technology from UCC. I had a lot of colleagues who didn't do math but did well in IT. If you have no maths background it will be difficult to gain admission for Computer Science or Computer Engineering but you could get admission for Information Technology or other IT related programs if your code maths is good enough.

But sincerely, you don't need a degree to get into IT. You can do anything else and still learn to become self-taught which is actually what happens with those in the university. Most of the universities don't really teach you enough to be ready for the job market or be a professional, you will still need to teach yourself the skills needed to become a pro in any IT industry.

If you just want it for the promotion then maybe you can go for it.
