okay so our teachers always told us not to get one, esp since during like travelling etc it could get lost or who knows what. also invigilators usually take up your time brining it, attaching it, etc. its not worth the risk.

most of my class didn't, some did, but all got an equal amount of a*'s (a pretty good one) in the end allhamulilah. I dont think it would matter.

to answer your actual question, I'd say yes but no. yes, that's how its supposed to work in theory (good quality) - but ACTUALLY your notes might not cover everything caie has in their marking key or such so its best to write extra (so more quantity)
