@Shadowlink Nah some definitely blurred together for me, especially...
1. Almost everything in SNES MK, which is weird because I spent a LOT of time playing it, but there are only like 4 or 5 different environments for the courses so I don't really remember which was which.
2. Almost everything in the GBA MK, but that makes more sense, since I barely played it.
3. Bowser's Castle / Rainbow Road from Double Dash to the present. I usually like these courses, but they all kind of use the same few tricks nowadays so I can't remember which is which.
