Need advice on grid

I didn't draw fancy lines or anything. On my first PCS I wrote my safety mnemonic, but I realized I was doing the steps during the PCS without referring to my "grid" and just left it off. I wrote my mnemonics on the back page but in no particular order except the 20-minute check was top left on the page. It helped to jog my memory when I was in the patient room to make sure I didn't leave out any critical elements, but since the number of assignments were different for each patient and some were long mnemonics and some were short, I didn't have a plan for lines. I was thinking outside the box. :) Don't get too wrapped up with this one. I failed, but I had good mnemonics.
