Friends please help me-I am an 17 yr old orphan boy living in my aunt’s house?

Don't give up:) do your best because you deserve this. I would avoid caffine because that will make you crash, and wouldn't suggest pulling an all nightdress either, because you will be sleepy during the exam. Study late, but not all night if you feel like it will make you too tired to ficus during the exam. Good luck:)
