Take MATH 144 and MATH 125 together？

Hi guys! I’m a first-year student in the Faculty of Science at UAlberta. I’m wondering if taking MATH 144 and MATH 125 in the same semester would be a heavy workload.
I also have to take PHYS 144 this semester. Does MATH 144 need to be taken together with PHYS 144, meaning that I can’t switch MATH 144 to MATH 154?
If anyone has taken these courses together, I’d really appreciate any advice or insight. Thank you!
