i don't think its the mode - it's the mean or median - most ppl at my school put it ... not sure though









reply back if u can
Mean, I doubt because of influence of outliers...
Median, taken into more consideration but still I don't think its median as mode when taken into account, seems more accurate.

Not too sure if guys are still interested, but the last question (finding the general expression for n) was:

[FONT=굴림]1/4 n^4 + 1/2 n^3 + 1/4 n^2[/FONT]

If you guys were able to see that the pattern was a quartic, you may have been able to solve it by simulataneously solving it!

But I'm starting to think from this discussion that I didn't need to go through with all that labour!!!!!

Was it OK to just put 1^3 + 2^3 + 3^3 + ...... n^3???

it just sounds to easy

for example if u get 60% divided by 2 = 30 + 50 = 80 %

so practically band 3 to band 5

doesnt it sound to easy for anyone??

and is this how they do align the marks?? and r u sure ?? or is it just wat u think??

also want to say if u get 20/25 , 43/55 , 16/20
this equals 79/100

doesnt that mean u get 79% = band 4??

My science teacher and CEM have said that they do get aligned because they want to make the state look good and because of the varying degrees of difficulty between the exams in past years.
