Leaving cert question?? HELP!?

Well my leaving is starting tomorrow and im not sure what level papers to take. Im currently doin 3 higher level papers but i might take ordinary in them on the day because i havnt studied. Im not sure wether to or not. Whats more important gettin more points or higher grades? For example if i take higher in home ec i could get a D and that doesnt look to good? if i do ordinary i could get a B, that looks better when your opening your results.. D's arent great.. but higher points.. what should i do?
