It didn’t say what it did to completion times. If you reliably finish your exams with much time to spare and make small errors that you have trouble catching simply using the balance of the time to check, this may be a good approach. Otherwise, there are probably better approaches.
Could an easy way to implement this hack, at least temporarily, be to read things upside down?
More on quick sensory disruptions later...
Excellent! I’ll do my exams upside down.
ETA: It was a joke—I don’t really intend to do this in my future exams.
I’d recommend testing to see if it helps before trying it in your exams.
