I agree with Julie McCoy. Don't push yourself to study too much right after an exam (unless you have one the next day or something crazy). You will burn out.
If I have an exam in the afternoon, I will read my outline (and if there is a rulebook I will read the applicable rules) once that morning. Then I make sure to eat a good meal and feel as relaxed as I can before going into the exam.
You don't want to freak yourself out right before your exams.
Once your exam is over (if you're at all like me) there is no way you'll be able to study for the rest of that day/evening. Don't be too hard on yourself about it. Have a drink or two and relax.
Of course, I have an exam tomorrow and I'm not even done outlining for it yet. I ended up in the Top 15% last year, even with my general laziness. I'm hoping that my 2L slide won't sacrifice my GPA too much. But I'll be happy with graduating in the top 1/3.
Good luck with your exams
And enjoy winter break!!!
