Aiyo, sorry, it's been so long that I didn't know the O's is
being held now 
My dear, don't take your teachers' spotted topics as the Holy
Grail. When you spot topics by yourself, you're Not 100% sure that
these topics will come out, right? Same for your teachers.
Remember, the O's are Not set by them, they wouldn't be 100% sure,
unlike prelims or your own school exams.
Don't think it'll be so bad till you fail, right? Only 1 question,
right?
