How CIE calculate the curve

[JustAnotherPerson22]

As some of you might know, starting from 2011 Cie starting releasing the curve for a*

Some examples^
here's my question, according to them the maximum mark for the syllabus is 200marks which really makes no sense since (CX) is out of 160 for bio and physics ...
For bio it says 155 for a* which is probably impossible to lose only 5marks for an A*
anyone have any idea how this calculation works?

 

[roadtrip9o9]

this is igcse bro .. do past papers ull get an A -.-

 

[Bouchra]

This is weird! I didn't notice this till now! That means I should be happy about the A I got in Bio last session, because I know there is no way I could've lost only 5 marks overall. I tried to do some sort of calculation earlier and felt something's wrong since everywhere it is said that A in IGCSE means 90%+.... but when I calculated out of 200 it always was less than 90%.

 

[Fatima18]

Yeah that's true..Maybe a mistake from their part??

 

[Osmix1995]

no the 90% you are talking about is the curve they do b4 the exam like normally they do a curve same for all exams.... until students got to the exam and does bad....when there are more students who did awful in the exam .... they modify the curve ( gets lower in this case) for example in o/n for chemistry variant 1

you need 142 out of 200 to get A* , and 124 to get A

here is it check yourself

oh and the table above shows what is the minimum mark for A in each paper get 3 A's and you have a A*

 

[Osmix1995]

o/n 2011

 

[Hamzeh S]

paper 3 is 50 % and paper 6 is 20% and paper 1 is 30% it will give u a mark out of 100 multiply it by 2

 

[Hamzeh S]

Actually if u got 3 A's but low a's its an A you need some high A's for an A*

 

[Fatima18]

How about in B.S?

Isn't out of 180??????40 for paper 1 ,80 for paper 3 and 60 for paper 6?

 

[Hamzeh S]

No paper 6 you convert it to 20 and paper 1 to 30 and paper 3 to 50 this will give u a mark out of 100 then multiply it by 2

 

[Fatima18]

No paper 6 you convert it to 20 and paper 1 to 30 and paper 3 to 50 this will give u a mark out of 100 then multiply it by 2

How about for B.S?

 

[Fatima18]

So let's say you get 45/60 for ppr 6, 35/40 in paper 1, nd 65/80, that gives you 163.75 out of 200...is that right??? Is it the same for chem and Geo
How about B.S???Thanx!

 

[Hamzeh S]

How about for B.S?

Physics Chemistry Bio , for english its 70 percent for the paper writing and 30 percent for listening each subject is different check syllabus it explains it all

 

[duck1300]

paper 6 has 40 marks each mark counts as 1. paper 3 has 80 marks each counts 1.25 and paper 1 has 40 marks each counts 1.5.
so 40+100+60

 

[zaid1q]

paper 6 has 40 marks each mark counts as 1. paper 3 has 80 marks each counts 1.25 and paper 1 has 40 marks each counts 1.5.
so 40+100+60

like i multiply each paper with my mark x 1 , x 1.25 , x 1.5???

oh and the table above shows what is the minimum mark for A in each paper get 3 A's and you have a A*

if i get the minimum of an A according to the TS..I GET AN A*?!?!?!

 

[zaid1q]

paper 6 has 40 marks each mark counts as 1. paper 3 has 80 marks each counts 1.25 and paper 1 has 40 marks each counts 1.5.
so 40+100+60

like for example chemistry MJ 2011 GT... lets assume that i got 40/60 in p6, 60/80 in p3, 30/40 in p1......to get my mark from 200 i multiply (40 x 1) + (60x1.25) + (40x1.5) = 175/200 and the GT for an A* is 134.... iam getting a high A* :O ??????????? is this the right way to calculate it??
