Dunno why you posted this since obvious us saying "you're fucked" isn't going to be helpful. I guess you're looking for motivation.
Study hard tonight, it's one night/day and it's all over. It's the final push. And I mean if you only started yesterday it's not like you've been studying for it too long to be sick of them haha. You'll be fine, read over your notes and go through everything tonight - work on any weak spots tonight, save tomorrow for light revision / no heavy learning to freak you out. Wake up early-ish tomorrow and recall everything by reading through your notes again.
Stay calm at all costs, don't give up, but don't freak out, just have a healthy amount of adrenaline/anxiety and hopefully your memory kicks in.
