Can anyone tell me how r A*,A calculated in various subjects of Igcse like maths, physics and chemistry??
Thankxxx in advance
-
it's different each year,
e.g. in the Nov 2008 session, a 44/80 in the Chemistry Paper 3 was an A
u can check the gradethresholds at www.freeexampapers.com
oh, and one more thing, there is NO A* in a separate paper, e.g. u cant get an A* in Biology Paper 6
hope i helped ;)
-
Ya i knw tht but like how A* is calculated in whole like in maths both papers if i get A so my overall will be A*
Anywayz Thanks

Anywayz Thanks
im not sure about this, my teacher told me that
A + A = A*
A + B + A
B + B = B
C + B = ?
C + C = C
hope i helped this time ;)
-
ya u helped a bit am still confused and nervous
well thankxx anywayzzz

dont worry about ur grades now,
do ur best and u will get the mark u deserve,
best of luck ;)

hey...
i thot the grades were calculated in a different manner...
like in chem/bio/phy
P1 is 30%
P3 is 50%
P5 is 20%
than yr total is calculated
if u get 90+ its an A*
80-89 its A
70-79 is B
n so on n so forth...

no, no,
there is no set percentage for a certain grade,
but ur right about the Paper 1 = 30 % and Paper 2 = 80 %
gd luck ;)
-
no way ppl even a frnd of mine got in math 71 its an A*.
even if it was A+A=A* believe me the whole world's gettin A*
the way they calculate marks is pretty strange.
and i dont thin 90+ and only 90+ is an A*
-
it depend on the graph
if the paper world wide is hard
for instance if candidate 70 percent ( hgighest)
trhey shiift the band of A* to 70
so on

Thanxx every1 i guess hav to concentrae on examzzz nd nt the grades for noww
well can any1 rep me for this question if they think so :) ;)

hope v r all gonna get A*s..
if i did get all the expected reslts..i would cry in happiness! :o
wnt u ppl??

They calculate the total marks of the papers in the subject 4 ex maths, the total is 200. then they plot all our marks on the curve., (like a cummulative frequency graph sort of thing )they usually decide the % that should take an A* so if they decided that 30% should get an A*, then, they calculate the highest 30% of us and the lowest mark from those 30% will b the A*.so thats why it differs from subject to subject and from year 2 year..... hope u got it... ;)
-
hOpe this year the curve is low!!!
Lets all pray for that!!
-
are grade thresholds decided b4 or after exams are taken by every1??

after the exams are taken and the papers are marked

ow thanx :)

This will give you all information required about gradings
-
its different every year nd yes it depends on the curve of the whole world
like for example in math paper 4.... if most people around the world got over 120 then 122 or 125 is an A
i'm just hoping that the curve is low this year for all subjects
-
I think that they make a cumulative frequency graph for each overall subject (for Maths, Papers 2 and 4 combined) and on the x-axis they plot the marks available (up to 200 for Maths).
Then on the y-axis they plot cumulative frequency and calculate the 95th percentile for an A* and read off the graph to see what mark corresponds to it (just like in questions we do as in interquartile range etc.).
If lots of people did badly, then the graph will be very high very early on the graph and low at the end (where there are most marks).
Do you all think its like this? (I'm confused too...)

they dont do the 95th percentile nd these stuff
just imagine that no one got above 95%...... then wat?? they re no A's or A*'s in math?????
its like how i said abt the curve nd that is how it was explained to us by the teachers

Guyz it is all comparative marking....
It depends not only how you do...but how all the others are doing around you...
Even the marking scheme is made by comparison...
So this means that it depends on the stupidity (or rarely intelligence) of the candidates, and on the difficulty of the paper...
This is the reason why some years the marks for A are so high and in other years they are really low.
So if the paper was really hard and every1 was getting a really low grade then the Grade threshold for the year would be low....and vice versa...
for example in 2007, you just needed 64.5% to get an A....
That is a really low mark if compared, but in that year the papers were really tough... I personally know it cuz my brother left the last page in maths paper 4...BUT HE STILL GOT A*....Cuz paper was hard... and he did most of hard questions... and he got the marks over there....and therefore even when his marks were low he got A*....
They calculate (at least for physics in the following way) ---> 100*((.3*(Mark In paper 1/40))+(.5(Mark in Paper 3/80)+(.2(Mark in paper 6(or 5)/40))
Then they decide a grade threshold...
they DO NOT release info about A* to the public....
There are many rumours about how it is calculated...
Some people say --> difference between A & B equals difference between A and A*
Others say --> mark for A grade plus maximum mark divided by 2 (average of max mark and A threshold...
Some people say that it is plotted and the a percentile is taken....
Some say that if you get A in all papers you get an A* on the report card
There are many stories like this...but we will never know how to calculate grade for A*, Though we can calculate our final grade....
As I showed above.
By the way i hope you've read in the markings schemes that A* is not available at the level of a single paper.
Hope it helps

Thankzz a world guyss so many different methods but no prbzz
thnkx for the effort we can now just concentrate on our examz am goin for the englsih second language paper 4 listening so pray for me

Gd luck, and dont worry, its JUST an exam ;)

i've heard that if u get maybe 2 very high As, like maybe close to full marks or little less, and maybe a high B for 1 paper, its possible to get A*...
cuz what if someone gets 76/80 in paper 3 (science), 37/40 in paper 6 but a 36/40 in MCQ, where 37/40 is A - so will he get an A overall even tho his weighted score with all papers is like 90%..?
this way, sum1 with an overall lower percentage may get an A* just cuz all his papers were at least A, even tho another person got a higher overall percentage but maybe a high B..

Grades are calculated by Obese CIE and Edexcel examiners.
