Wondering if retaking a course in 4th year would be beneficial at all

Hi, so essentially I took MAT237 in 2nd year and didn't really do too well (I didn't really do too well overall honestly in my first and second year) but I've grown a lot as a student since then so I was thinking of retaking MAT237 firstly to actually learn the material better and secondly to show that I've grown as a student in math in case I want to apply to grad school. Any thoughts on if this is the move?
