Always try to balance everything.
“All work and no play makes Jack a dull boy.” It is a proverb. It means that without time off from work, a person becomes both bored and boring.
So you do study but you also take part in playing. B/c healthy body contains a healthy brain.
Physical activity is very important for your health.
Health is first then study. But very strange you play while exams. It’s simply a solution of failure. Don’t do that.
