I really don't know if the Zodiac gave me a good idea or a bad idea.
I remembered watching Doraemon when I was a kid, and Big Xiong was just as bad at school as I was, so Doraemon gave him the memory bread, and as long as he printed what he wanted to test on the bread and ate it, he'd be able to keep everything in his head.
The method the Zodiac told me is kind of like memory bread
