Cheat sheets, I wasn't sure what you mean as I think there are two definitions so I had to research LOL! Cheat sheets for cheating in an exam I think I've done that once when I was younger.. Wasn't worth the risk tho cos I felt guilty LOL. Cheat sheets, like writing down notes repeatedly just to remember them, yes! Many times and it literally saved me from failing. Hahha. There are different types of learning and some listen to the words, etc etc. It's a good thing we have the same method. :D
I also agree with putting notes on phones and electronics. I dunno, but I also forget them a lot but when I write them down, I remember them easily. Lol indeed the human mind is complex and very interesting :D
Hahahaha the first cheat sheet form you mention is the one I try to refer to :)
hahah well at least I sent you two answers! :P
