You do not need to be very good at math to get a CS degree. The last role I had was in a company heavily loaded up with UMich CS grad students, none of whom could (for instance) deploy a discrete cosine transform.

There's a level of "street math" that good programmers tend to have (statistics, maybe some trig, maybe basic matrix arithmetic), but you'd be surprised how many excellent programmers don't even use algebra. A friend of mine interviewed at a very famous quant hedge fund (a decade or so ago) and shocked his interviewer by answering one of the questions with a system of equations in two variables.

I'd expect UMich CS to be very strong. I haven't looked at the undergrad curriculum, but I'd be surprised if it doesn't require calculus through differential equations, along with some more advanced electives.

I should have defined "tough math," because a lot of people on HN have gone far enough with math that what I described above wouldn't be considered "tough". But it actually does serve as a gatekeeper for most engineering and hard science curricula, including CS.

One can get through the required classes without being any good at them. Wannabe doctors take 2 years of chemistry as premeds and promptly forget it all when finals are over.

That said, I've never seen a CS degree that required any more math than a year of calc and maybe a semester of linear algebra. That doesn't seem so hard, one just has to keep up with the homework. Maybe you are thinking of computer engineering?

Semester of statistics required for mine.

Of course they have since dropped the stats requirement. And the calc 2 requirement. So now it's a semester of calculus and a semester of linear algebra. I guess too many people failed calculus 2 and stats.

People fail stat and pass linear algebra?!

There's basic "stat" for the social sciences (nothing but arithmetic for means, medians, standard deviation, and so forth). Then there's calculus-based probability, which can be very rigorous. The CS curriculum at rigorous programs tends to require the harder, calculus-based probability. I was a math major, but there were a lot of CS and engineering students in my stats class.

BTW, even with the calculus prereq, I'd agree that linear algebra would typically be a harder class, so I definitely understand why you're surprised someone would pass Linear Algebra and fail Stats.
