Rosie: thanks
Hannah: you're ready for it?
Rosie: not sure but I can't study anymore
Rosie: I think I'll just go to bed and rest
Hannah: that's not a bad idea, just rest and relax and everything should be fine
Rosie doesn't feel she's ready for the exam, but she can't study anymore. She'll go to bed and rest.
