New to the O levels things...

I am currently clueless... For the O levels test (Islam) will all the topics I learned from grade 1-10 be in the test? Or just 9-10? (I use e-books to access the higher grade books).

How can I study? Will the question be very straight forward? Do I have to be good Dhivehi? (I suck) Will the hadith have to be memorised/understood and get certain points out of? Is there more?
