Contract Law Study Hack: "P's and C's

Yaar, I remember this one thing that helped me recall the types of consent - express and implied. Jab tum log mock tests dete ho, I needed something quick and this worked: "Papa's Cake" - Papa is Principal, Cake is Contract. The more obvious ones (e.g., Express - Direct/Captioned, Implied - by Conduct/Inquiry), I linked to the first letter of the word (P for Principal, C for Contract). This simple association made it easier to remember. Don't know if it's foolproof, but it helped me pass CLAT PG. You guys got any better tricks?
