In my experience, I can probably say that Criminal Justice does not require math, although that is a weird course when it comes to math. Sometimes it is an option, sometimes it is required, and sometimes it is not needed. For me and no matter how I looked at it, it was an option, my college told me it was optional (Although they could've lied, it won't surprise if they were) or I could've skipped it entirely if I was chosen in High School for a certain program where I take the class in High School and it would've gone towards as full credit in college if I did well enough (And I was, although I didn't get full credit because I dropped out of the program because I was not doing so good in it at first. I wish I didn't because I ended up doing good enough by the end that it would've been given full credit.). From what I've seen from some colleges, and this only to American colleges because I do not know if any colleges outside the U.S. do something like this, it will be required if you didn't get a certain score on an academic test or if you didn't take an academic test and it won't be required if you scored high enough. Mostly from what I have seen for Criminal Justice in my experience and from what I've seen from some other colleges, you'll have to take a College Algebra class, which in my experience isn't too difficult (If you take the time to study it, and you're given examples on how to complete it and you study those examples and you don't rush it, it's kinda easy, there are some parts that I still don't understand all that well, but it was fairly easy after a bit of studying.).
In terms of what you are interested in, I've taken a look at some colleges and they all required some sort of math in those courses. Pretty much anything that deals with science or technology has a high chance of having math be required since math is like science, they are both complex and need to be broken down into small pieces to be fully understand them from the inside and from the outside and the smallest change in something may cause a giant difference in what happens.
Here's what I advise, if you do end up taking a course that has math then you want to 1.) study, that's a key thing when it comes to math, lots and lots of studying and you want to study it no matter what, you want to memorize every single bit of what you doing and get to know it, 2.) take notes, write down every single little piece of detail about it, and study that as well because if you can't use your notes on tests then you gotta memorize how to work them out, 3.) if it is at all possible, ask your professor or instructor for help in trying to understand how to work something out, take notes on what they say and study it, and if you can't then you move to number four, and lastly 4.) if your instructor or professor is unable to help you, then find an outside source, maybe some friends, classmates, possibly the internet (Although the internet can be a bit iffy at times.), find out how to work it out with or from them, take notes, and study them. Studying math is the most important part, because like I said, math is like science, you need to study them if you want to fully understand them. I know how it feels not to good in math, I was not very good and I'm still not that good when it comes to math, that is why I took every chance I got to try and get to know it even though I really didn't want to and got sick of it, but trust me when I say that studying math a lot, taking notes on it, and finding out how to work them out with some explanation helps a lot.
