In UK when your about to do you GCSES (General Certificate of Secondary Education) the first proper qualification of leaving school, most schools send you on study leave. This is where you stay at home and study for your upcoming exams. PROS: Can study in own environment, can feel more relaxed etc, wont have to be at school whilst other exams are on. etc.
CONS: At school some people are more likely to study, you can ask teachers for help if necessary, all resources are there if needed.
The last one on the cons list might not be valid because you would take resources home, but there are always people who forget.
