Yes I shall pray for your success. I would not worry too much. Try to learn small manageable amount of information. It could make a significant difference for you. Even if you do not do well in this exam, you will still have many options opened to you.
may Allaah :arabic2: grant you that which is better for you. Aameen.
"Failure" in the dunya is just a part of life. Don't worry about it. People just try and get you down by making it appear like the end of the world. Don't give in to them. Real failure is disobeying Allaah :arabic2: and ruining your aakhirah. Real success is attaining the pleasure of Allaah :arabic2:
And besides, how do you know that doing badly in an exam is not actually better for you? You don't. Only Allaah :arabic2: Knows.
Something I read recently: Sometimes Allaah sends us failure to make us humble.
