Hello,
Considering I don't know what text you're referring to, I'll just answer the question as defining it.
A refugee can be defined as a person who is forced to leave their country to escape war, persecution, or a natural disaster.
Answer:
Review the test material daily before an exam
Take short breaks and make sure you are well rested.
Set aside time for yourself during the school week
Explanation:
the rest are really bad ideas. you need to study when you are alert, not in a dark room where you will fall asleep
take your textbooks and notes with you everywhere. study whenever you have time. dont leave them at school, you need them.
dont talk to your friends, you cant be distracted.
