my experience when i was grade 12 I learn hard play harder not serious about learning. Each day after school friends will go to tutoring. But I am going to relieve stress. If I stress I will read novels, watching cartoons to relieve stress. When examination i will read books to review of all study. While each friend stress about the exam, but I don't feel bad. When the announcement of the exam. I have a lot of points than my friends too.
From this example. That learning outside the classroom that no stress better learning is full of stress.
