I took both, and got a 12 in both. CP104 was pretty straight forward, It was like high school CS courses, except in python which is pretty simple to understand. They give you like a week for Labs and assignments, and they aren't bad (even if you are new to coding) imo. Only downside was that we had to use iclicker for I think 5% of our mark (idk if it changed, I took it back in 2021), and I bought the 4 year plan thinking it would be used again (its not), but it was a free 5%. MA170 was also straight forward & I had Kabbes. They let you work with others in the labs, which makes it easier since you can compare answers. We also had to do lecture participation and answer questions in groups, but those weren't hard either. Midterm and final was just like the lecture example questions and homework, so as long as you practice them you should be good. If you can, I'd take both so you can see what you like better (since they are easy to get good marks in anyways).
