42 or 41?

 

[Ayesha Asif333]

Are you forgetting that stupid half life question?

Nooo thats y i mentioned in the beginning the no. of marks ill lose
It's the theory that'll save me or else i suck at phy calculations

 

[Adeen Atif]

I'll lose max of 6 marks, i think
We got
No Dc motors question
no Ac generator question
no use of flemings rule
no scale diagram
no barometer/manometer question
No sch hc ques
Nothing related to force and extension
What more do we need?

And all these things ur grateful for not coming,All of em were my strong topicsExcept for barometer ofcourse

This so happened with me in maths
I was good at vectors, sequences, sets but they didnt come
there's nothing much we can do abt it now and if u know the mistakes u made u can learn from them and this paper is definitely not the end of the world, and not even worth the tears and regret

Oh
Yeah, We tried our level best.
And whatever we,ll get will not be that bad.

And I suck in theory and love calculations,but this time calculations stabbed me in the back

Fortunately, for u then the numericals did came...but it turns out they left a mark at your back
And remember when i said earlier i like phy but phy doesnt like me back

Yeah,I guess Im in the same boat as you now.

can you believe we got aall of that in 42 except for hookes law and barometer
and the paper was so lengthy most people couldnt complete it
man, i think i'm gonna lose like 10 marks man, will i still get a A*
my paper 2 and 6 were really good tho

 

[Aayan Muttaqi]

My paper was 16 pages long, relatively easy paper , the half life was slightly annoying though.
Theory questions were there. Numerics were not as much , like 40% calculations and the rest theory.

 

[Aayan Muttaqi]

Anyone sitting for computer paper 2 tomorrow?

 

[Munib Ahmed]

who gave p41 for physics
what was the answer for the radio activity question that contained the table?
what was the answer for the question in which we had to find the direction of balloon by calculation (4 marks)
what will be the expected grade threshold

For the radioactivity question I averaged the count rates (once they stopped decreasing) and I got ~19 counts/s <--background radiation (BR)
To find the half life, I subtracted the BR from each value and noticed that after every 2 half lives the value was close to the count rate every 1hr
e.g 324-19 = 305 etc ... 305/2 =152.5 > 152.5/2 = 76.25
And after 1 hr the count rate reduced to 77 c/s
So... 1hr~ 2half lives Thus 1half life ~ 0.5hrs

 

[Ayesha Asif333]

I hope there is a range for the answers....for the count rate from 18-20
And for half life 0.5 -0.67 hrs....i just hope all of these ans r marked correct

As for the balloon the calculated density of ot was lower then the density of atmosphere so the balloon rises upwards

I think it will be 147 for an A*

Yes i do believe
I thought u said u've never lost more than 7 marks, but ten is nothing...u can get an A* at a loss of 30 overall
And can u believe the gts for m17 was 134!....i hope ours be this low
Good, that'll perfectly over up the mistakes u've made in p4

 

[Ayesha Asif333]

And whatever we,ll get will not be that bad

In sha' Allah ...it will be good

Yeah Inshallah, All our hardwork will pay off at the end.
BTW ,Did you both get your login details yet?
