How to view the source code of a link that keeps redirecting?

I am attempting to view the HTML source code of the following link like so in chrome:

view-source:https://rankyourbrain.com/mental-math/mental-math-test-easy/submit

But it just redirects to

view-source:https://rankyourbrain.com/mental-math/mental-math-test-easy

What is happening? Is there a way to prevent this (or view source another way)?

Also, let me know if this is the incorrect forum to ask this question...
