How was Physics P42

[issac0215]

If you're talking about maths, then yes.

nope..i mean phy >< my friends were all shocked after the exam..

If you're talking about maths, then yes.

Definitely for math!

 

[AhShun]

Cause it's true I don't have problems with either, and p5 is especially one of my favourite papers All the best for both papers!

thanks same to u too

 

[good man12]

So wat u think A* will be for maths? Can it reach 195? I don't think

I predicted that there are 95% chances that GT for A* in math will be from 203-213......

 

[123dawg]

How many actual calculations were there compared to written answers and I thought you only got deducted for sig figs once.

I think like only 25 of the marks were calculations the rest was written

Can you please explain to me the 203 gt thing what does it mean 203 out of what ? I don't get it

A* is out of 250 so 203/250 - 213/250

G for A* for maths always in this range, I'm sure I won't get A* cuz i am getting less than 200 A* in maths will never be <200

Oh ok so:
P1 out of 75
P3 out of 75
P4 out of 50
P6 out of 50

So if I think I got :
60/75 for p1
38/75 for p3
45/75 for p4
45/75 for p6
I am sitting with 188 out of 250 so like a B ?

yes, a very high B , or even a very low A

 

[123dawg]

yes, a very high B , or even a very low A

Oh ok great thanks so much for explaining

Autually ur calculations are wrong

P1 and p3 are both on 75 marks each

P4 and P6 are on 50 marks, totaling out to be 250.

u need to review ur p6 and p4 marks

yea i meant to say out of 50 for those, was using my ipad that i got yesterday and made the mistake

The discussion can start.. how was the graph for the opamp- how to get zat 4 marks

 

[W-inx]

i put all the details on how it's saturated but instead of square i put the sides curvy im such an ass -.- I put it saturated at 5 though with the dotted lines to show it's saturated

Dude ur really good at P6, I suck at it, the only paper i fucked up Ur p3 decreases ur marks though

You can definitely get an A based on ur pts. 188 is normally an A

i fink z question appeared in june 2012

 

[W-inx]

i fink z question appeared in june 2012

the wrong thing i did was the square form. Do you think they will cut only 1 mark?

 

[alcoholic 111]

I think this thread was made for physics p4 discussion not for the maths
if you expect 180/250 and you are pretty sure on that you would land on A grade
I gave in june 2012 and was expecting 190/250 ended up getting A*

Question No.1
change in kinetic energy as far I could remember was 1.0 x 10^8 J
Change in P.E was something like in magnitude of 10 ^-17 J
and the linear speed decreased because of loss in K.E from calculations ?

Can someone please take the pain to draw the graph of Op-Amp please
