yh one of my friends got exactly this
wut was ur gradient?

3.32
C was 2. something dont remember exactly

could you please please tell me whether this is the correct way to calculate our final grade or not :
MCQ score + p2 score + p3 * 0.75 + p4 + p5 .. lets say that the threshold says that 200 is required for A*,, now if all of these scores add up to , say , 201.. it will be an A* right? lol I am just a bit confused because I saw someone comment that " a total score of 218 might just touch A * " in a thread

3.32
C was 2. something dont remember exactly

lol oh my god i got it wrong
wait it was 3.32 ^-3 no?

lol oh my god i got it wrong

hmm i didnt take 10^-3 in gradient, but wrote kOhms in unit for C..

no it never goes that high
itll touch 200 n thats it
yess u can get an A* that way

unit for C was F or sohm^-1 i think

 

[Mts.99]

unit for C was F or sohm^-1 i think

i wrote in terms of s and ohm, not F, will it be accepted?

 

[Mts.99]

These are the right angles except for definition of wavelength and antinode
And the angle was 6.7
Also Not sure if the frictional force is correct

how was PD calculated in q6? i didnt get 3

yh i wrote so too
i think it should be

 

[Kanekii]

Can anybody remember in the question which asked about the two possible properties of Z, was same length mentioned or not?

Yes it was mentioned
Though i wrote about it had greater area and less resistivity is that correct?

 

[Error Syntax]

I got around 55000 and so did most of my friends is

 

[Kanekii]

how was PD calculated in q6? i didnt get 3

By this:
E= V + IR
Input values and find V

in the question related to doppler effect , even though the source was going far from the observer but its velocity was decreasing .. when we considered till 8s as mentioned in question. so should'nt the frequency increase

PLZ HELP ME
i got an A overall in AS
but a B in p3
n in MCQs i got an A but m sure it was a close one
my theory went fine...ill get an 80 or above that
but i messed up my p5
i might get 21 or 22
can i still get an A*?
Zaki ali asghar Holmes haithsoul Error Syntax guys plz help

For paper 52, did we have to take 10^3 for the nR to calculate gradient?

 

[A*****]

Yes it was mentioned

Yes correct

 

[Tauqir_hamed]

you are correct. the frequency increases. thats the correct answer

The minimum marks you had in AS were 88, but you must have gotten more as the threshold was for P2 was quite low. Now if you get even 80 and 22, thats an easy A* hopefully. Makes the total around 190.

 

[Zaki ali asghar]

I am in a similar situation here. expecting around 25-26 in P5. 80+ in P4. I hate myself for messing up Q2 slightly today

I wrote greater area and less length? Is it correct?
