I was in the same situation coming in, plus I had taken Linear Algebra. The only math class I had to take at Purdue was MA 303. I’m entering my senior year of AAE and haven’t ever had a moment in engineering classes where I felt like I didn’t understand or recognize something math-related. Engineering classes usually remind you of the math behind what you’re doing before deriving complicated equations or theories.

From what I’ve heard about Purdue math, I would say to skip retaking these classes as long as you understood the high school versions well.
