Time to rethink

So, What shall I study during the summer. The application opened up last Monday and I though I will study a 5 weeks course. But, what do I want to study.
I thought to apply to business or religion course.
The business subject is cross culture management, or analysis financial wealth in organizations or some other. The religion topic is about reading religion topics and analysis the texts.
But let see, I discuss with my parents to see if it is a good idea to study or work more.
