Narrative:

ZBW cleared us to descend from FL280 to cross 35 NM north of manta intersection. I was flying and had trouble inputting restr into FMS. Captain then tried, and no luck. Then ATC asked if we were going to make restr. I performed maximum rate of descent. I honestly do not know for sure if I made the crossing restr, but I feel I may have been a little high. I am relatively new to B757 and was unable to figure out FMS and neither did captain who had been on B757 for 5 yrs. I do think I possibly entered restr on other side of manta intersection.
