There's a really common mistake in this exam that I didn't anticipate. It's "integration by parts of wishful thinking":
The students integrate by parts, then "solve" the second integral (which can, in fact, be done by a second integration by parts) by wishful thinking.
I know my students love "integration by wishful thinking", but TIL they can also do "determinant calculation by wishful thinking".
You can do it for non-quadratic matrices as well!
