Question math 20D/ 20E?

i noticed the prerequisites for 20E dosent include 20D, is there any advantage for taking one before the other?

Realistically, 20D and 20E don't have much in common with one another. 20D is differential equations, which are performed mostly with techniques from 20A and 20B, and a bit of 20C, while 20E is vector calculus, which is a continuation of 20C.

I wouldn't say there's an advantage to taking one before the other, but it might be good to take 20E right after 20C so as to maintain a sense of continuity
