What Can I Say:

Do you know? that reading and studying Qur'an is not very welcomed in islam Only to succeed in an exam or in a competition or in an argument. The Scripture named Qur'an has revealed to us to study and to act as it says. Not to just have fun on it. Or else Mohamed, son of Abdhullah, had informed us "Hey people. I have brought you guys a book and a religion to just study" No. He, Mohamed (SAW) and all other prophets who came before were giving only one message. That is Islam.
So I advice you not to study this book for the sake of passing from an exam. What you have studied from the religion will be questioned hereafter. However, it does not mean that you don't have to study to avoid from being questioned. No, your laziness in all perspective towards Islam will be questioned hereafter.
