I feel soo guilty, what should i do?

i was talking to this guy i really like the other week and we were talking and psats scores came up (i'm 16). he asked me what i had got on mine and i said 1590. and he asked me if it was out of 1600 and i panicked and i said yea, except it was really out of 2400. i've felt really guilty ever since and i see him next weekend and i have a feeling he might find out. should i just forget about it or should i tell him??
