How did everyone find it?
I thought it it was ok except question 16 was a pain.

 

[Queenroot]

I screwed up most probability questions.
And the last two questions were a hot mess of random working out.

Other than that, I'd say "ok."

 

[dunjaaa]

The 2 mark probability, forgot the BH, BB, HB scenario, the clock chiming question I did 24 hrs instead of 12 and the question which asked for what values of y does this series not have an infinite sum. The play on words for the series questions screwed me as for a series to not have a infinite sum, means it has a limiting sum =( Sitting on 96/97

 

[Hypem]

It was fine at the start, but by the end it became very difficult.
Hoping for at least 80-82% (band 6 aligned)

Did anyone find it was harder than past papers? I think 8 marks allocated to the last question (c) was too much

The last question is always hard. I didn't even understand it.

Wait, the clock chiming wasn't a series question? OMG?

And yeah that Y value one was uh... yeah no...

 

[dunjaaa]

The thing about the chiming question, was the question specified a grandfather clock which obviously is not digital. And I did the sum from 1-24 rather then 2 x sum from 1-12

Just hoping to nail the extension 1 exam on friday

 

[lolwot]

The area of the triangle one I got like 1/6 marks... I'm so dumb...

I hated that little bit of rectangle on the side. It was so mach workun out for no reason.

 

[dunjaaa]

The last question all you were required to do was sub the value of pi/12 into the derivative of the area in respect the theta and test to show that it gives maximum, or you could use 3u trig double angle identities but imo for a 2u exam last question, it was pretty tricky indeed especially part 1

 

[dunjaaa]

For the rectangle subtended inside a inside the triangle, you had to use similar triangles, was very tricky, at least stared at it for a good 10 minutes

what the f...i won't even begin to speak about the last question. Worked backwards and pretended i knew how they got to the answer.

>says she won't speak about the last question







>speaks about last question

 

[iBibah]

I had a quick geez the last question and it looked quite interesting.

 

[girlworld_club]

lol

Hi Danny

 

[dunjaaa]

sup

 

[SharkeyBoy]

That question with the button that were either heart-shaped or had silver sparkles or both,
for the last part where is said: What is the probability of having exactly heart-shaped buttons - Were you supposed to calculate both 'heart-shaped' exclusive + the 'both' buttons? I did the probability of both. Is that right?
And I got the last question!! hahaha

 

[dunjaaa]

4 scenarios, HH HB, BH, BB

 

[SharkeyBoy]

4 scenarios, HH HB, BH, BB

My bad, the question said '2 heart shaped buttons', so then that would only mean HH, BB yeh?
