I am in the exact same position as you at the moment. Burnt out, and totally over studying and just learning in general. I have two exams to go, Chemistry tomorrow, and Food Studies on Thursday. I can't really say much, but the thing that is keeping me going, is that it's only a week to go. After that you are done, and you can take all the time off in the world. It's not much, and hard to actually follow when you just feel so ready to call it quits and just go i'm done, but it's only a few more days!
I like to think that even though current me is over it and doesn't care anymore, I know that future me does, so i'm working for her in the future.
If you're feeling that burnt out, i'd recommend half taking it easy and half pushing yourself. Say you still want to do those two exams per day. Take the morning off for just relaxing or doing what you enjoy, and getting those two exams in the afternoon. At the moment, i'm no longer doing exams under timed conditions, so the whole stress thing doesn't hit you as hard, yet you're still exposing yourself to content and revising.
I feel your demotivation, but it's not to long to go. Don't give up, and good luck with legal tomorrow!
