Have you ever done that, where you are studying for multiple different subjects, and you have so thoroughly immersed yourself in every detail of every topic that you… start to completely mix them all up with each other? I know I’ve gone into “Test A” with a keen sense of mastery of “Subject Matter B”, only to go into “Test B” remembering only “Subject Matter A”.

Although I’ve never quite mixed up factors of Porfirio Diaz’s decline in popularity with the steps of calculating C-4 charges for a 40-inch diameter tree demolition. I’d have to be pretty far down the rabbit hole for that.
