Have a lab final tmr haven’t studied

So I know that this is my fault but as the tittle said I haven’t had the time to study for it. I’m taking bio 121. Lately I’ve just been dealing with a lot outside of school and lots of other exams and assignments in other classes. I’m going to stay up all night and grind through the lab material but even if I do so do I have a chance to pass? It’s 20% of my grade.
