Physics IGCSE Grades/Paper 1 etc

[KareemXPF]

No I'm sure the question said that it didn't need boiling water.

i dont think so..
cause if the question is which does not need boiling water.. the answer would be the 3 other then nuclear fission
plus .. that question is repeated and i solved it before

its ok bro we all have mistakes
concentrate on the next paper 6

 

[KareemXPF]

What about the half life?

What was the question cause i forgot

 

[KareemXPF]

If i remember well..
the answer is 100mg... the substance was originally 400mg and its halflife was 5 days.. and the question asked to calculate the mass left after 10 days.. so it is 100mg

 

[unplugged]

Pretty sure that's how t he question looked.
I did it wrong as well , was rather absent minded ;p.

 

[DowntownCrew]

You are right about both Kareem.Half-life question was 100mg and the question about energies was Which of the following is first boiling water and the answer is nuclear fission.

Hope to get at least 30 in paper 6.40 maximum ??
Hope thats enough for my grade C

 

[KareemXPF]

Well .. 30 is rarely enough for an A .. I just look for an A* ... i did well in paper1 .. around 2-3 mistakes.. i wanna do well in the other papers..

Guys how do you know the curve of an A*?
in the threshold it starts with an A..
If maximum mark is 80 and minimum mark of an A is 50 .. then we will 80+50=130/2 = 65?
So 65 is the min. A* mark?

 

[Keeemoman]

No it would impossible be that as they mentioned no A* in individual component
It could be based on the world performance. if the exam was hard then this means that 60% could be an A*
It could be also by combining the papers
If you get all A means this you can get an A*

 

[KareemXPF]

hmm..
So if i get 37/40 in paper 1
68/80 in paper 3
34/40 in paper 6
Will i get an A* ????

 

[KareemXPF]

Answer me guys please .. im so worried :%)

 

[KareemXPF]

Hey guys.. Cant i get 1 answer? :S
if i get 37/40 in paper 1
68/80 in paper 3
34/40 in paper 6
Will i get an A* ????

 

[KareemXPF]

Lol guys.. arent anybody doing physics? !!

 

[HorsePower]

u cant really say that right now becuz we havent seen the difficulty of paper 3 and 6 yet.

 

[Keeemoman]

Lol guys.. arent anybody doing physics? !!

of course man
This even could be world rank
If you get in 50s or even 40s out of 80 in p3 you may even get A*

 

[cheesww]

if i get 35 or 36 out of 40 in paper 1 physics does it mean my chances of an A* r dead?

 

[Gunner1995]

NOOO! Ofcourse not... THATS AN A* For sure. Last year it was an easy paper and the A* was a 35, This year it was much harder than last year. Keep your chin up
