and the next question was what??

had to calculate volume if length is 15.

I multiplied 78*15

 

[moh321]

thats right!! even i got 78!! hi5!!

I don't understand this equation can you explain

yes i got it!!

 

[misscute406]

also linear programming, vectors

So paper 4 will most likely feature transformations, compound and simple interest, and function graphs

I don't understand this equation can you explain

the barn was made of a rectangle and a triangle on top
area of the rectangle was 12 * 5.
area of the triangle on top had a base of 12 also, and height of 3 (since whole height was 8, and we subtract 5 from the triangle off) so 1/2*12*3.
add the two its 78!

Lol lucky u... did u got any question with infinity i mean with number with dot above it and then u have to right it in fraction
like the Q.4 in 0580 specimen paper 2 2015

Yea.. seems like 21 and 22 were similar

 

[misscute406]

Mostly paper 4 would feature:
-Variations
-Interest
-Money Exchange
-Functional Graphs
-Linear programming + Inequalities
-Bearings
-Symmetry
-Circle Theorems
-Trigonometry
-Probability
-Vectors
-Transformations

Oh.. and what was the answer for the second last question of sets...
'P is a proper subset of M'

 

[misscute406]

what did you write i dont remember ??

[Saad the Paki]

{1,3,5,7,9,11}

 

[Saad the Paki]

But i think it shud have been {1,5,7,11}

 

[Saad the Paki]

And for the locus question... was the diameter 4cm or the radius?
And u gave 21 right misscute406 ?

 

[misscute406]

nopee Saad the Paki i gave 22!!

 

[NOneed2speedd]

{1,3,5,7,9,11}

^i wrote same

 

[misscute406]

i did that only!! I wish its right!!

But i think it shud have been {1,5,7,11}

t

 

[moh321]

i did that only!! I wish its right!!

I did the same . Does anyone know max marks we should lose to get A*

 

[misscute406]

I did the same . Does anyone know max marks we should lose to get A*

I have no idea!! :3

 

[masterex567]

Btw, what if you perform poorly in one paper but the other you have almost full marks and your overall percentage is 86% or something above.
If the grade threshold is around 80 for an a*, will that count as an a* or is it a must to get an A in both papers? and not overall only
