As above you've got two choices,
1 - Turn it in late and only get a pass regardless.
2 - Cobble something together and get a referral and then try and get a higher grade. There's nothing to stop you keeping a copy and working on it while you wait for the referral.
Whatever you do don't cheat, if they catch you you'll get booted instantly. My tutor told me that all colleges running Access Courses use plagiarism detection software to check assignments, so if you try and copy something that's freely available online it's likely that you'll get caught.
