I would say stick to Computer Science or "IT" - in real life, you are less likely to be doing advanced math work all the time and if you were required to do it (in case you were working with data science or stuff, companies usually have data scientist or math people who have to make the math checkout at the end of the day, so you will get all the help you need)
Another way to go around it is to calculate how many grades will depend on math, what is their weight relatively to the total and see if you can make it.
Ask the teachers to sit on a math class and see how it sounds.
A last alternative is to take the business classes, learn about this stuff because it is important in case you want to do your own startup in the future and then have extra curricular studies in computer stuff or learn yourself the technology or participate in bootcamps or free programs like this

Good luck figuring this out. Not easy!
