one done more four to go

Our 1st pre board exam started from today , Economics was the 1st exam, now more four exam I have to face :( can you tell who introduced the concept of exam? i will kill him/her.
well I had attend the questions of only 70 marks and in hope that I will get about 60, now lets see how much I will get. Actually I don't understand a single word in economics,I just hate this subject don't know why? I just mug up the lines of this book. Well next exam is accountancy and its preparation is good enough.
