My Semester 1

So....I had STPM Sem 1 last few weeks
Pa and Maths T was okay for me, cause I can do some of the questions.
Then i was busted by Bio and Chem. T.T
I don't really know what's the bio question asking for -.-
Now I knew, Bio question is so weird.
We studied Chapter 5 and 6 like crazy but they don't even care to give us an essay question about one of the chapters.
WHY!! 
And Chem, the question was so hard, for me.
I can't finish the paper and i left some blanks in the essay section. *sighs
I felt bad as i scored the highest mark for Chem and it was the only paper that i passed during my trial.
And our reputation in school depends on our Sem 1 results.
Just hope I could pass....or prepare for retake.
