Is it possible?

Finals are coming, and it seems like I am going to be crying and burning midnight oil at the same time. For people who know me, they know how 'kiasu' ( afraid to lose ) I am, and I definitely take my exams and stuff seriously, especially if it is going to cost my scholarship. T_T

This morning, or more like afternoon, I went to check my assignment and midterm marks, and I thought they were fine until I got home to count. So... Let me write down some mathematics equation here.

Hmm...

Coursework = 85

Coursework takes up 40% of the whole 100%, therefore, how much when we convert 85 to 40%?

EQ:

85/100 X 40 = 34

So, I get 34/40. So, to get an A, means 4.0 GPA for that subject, I need to obtain 80% overall. So, how much more do I need to score in my finals in order to get at least 80%?

EQ:

80 - 34 = 46

EQ:
Let's set the marks during finals that I need to score as 'y'. The finals take up 60% of course.

y/100 X 60 = 46
y= 76.6666666
= 77%!!!!!

Waliao weh... That is almost impossible to me!!

The other one is also the same, just that the coursework marks are 80/100 only. So, let's count that one. ( Coursework takes 40% and finals take 60%, variable for finals will be 'z' )

EQ:

80/100 x 40 = 32

The marks I want ( 80 ) subtract the marks I already gained.

80-32= 48

The marks I need to get for finals in order to gain an A, which is a GPA of 4.0 for that subject only.

z/100 x 60 = 48
z= 80%!!!

I give up..... It is almost impossible... Aihz...

I'm really going to cry my tears away now... Sobs.....

This serves 2 points here. One, is to teach you mathematics, and primarily is to tell you, I WANNA CRY.....!!! ( If I did my maths right.... ??? )
