Someone remind me what question 6 was.

(3root5)^2 is 45 right? My mind went so blank 😂
yeh
3. The exam was horrible. I swear every question had a big fraction in it. :/

4. You remember what 6 asked? Was it that one where you had to use the quadractic formula?
5. (Original post by craigie435)
you had to use pythagaros which got you route 64
Thought it was root 65?
6. (Original post by ExamsCauseStress)
You resit it in your A2 year and it is the best mark that counts, so no reason to not resit tbh!
That's super useful then...also, do you know if students have the choice to resit even if they achieve their target grade but want to do better?

i believe b(-3,4)

integration = 20.25
Q = (-5/4 , 0)
Cant remember my P line
Area = 20.25-9 = 11.25
No b was (12,-7)
C was basically the midpoint of AB as AB is the diameter.
so you basically had to approach it this way:

(x+-2)/2 =5
and (y+1)/2 = -3

For the coordinate of Q, I left it I simplified as -40/32, (which is the same as -5/4) but was wondering if I would love a mark? Was it just worth 1?
well most of the times, in the mark scheme, for these kind of answers you get an abbreviation of OE which means Or Equivalent.
so I'm guessing they will indeed give you the mark.
9. How hard do you think C2 will be?
10. Jhons uncle is gonna be paying for my resit👀👌 #C1
11. No it should be (0.5,41/4)

I found it alright but struggled on the question where it asked for CT and gave you AT
Pythagoras was what you needed to use. Luckily my teacher has been telling me all year to draw pictures. And that helped.

How did you guys find the value of k? (in questions 6 i think) I just guessed and put k=4 :/
I believe k was 30 or something like that

Anyone else get

x = -1 plus or minus root 5?
Yes ... Do you remember any more of the questions we answered
15. (Original post by melanin101)
How are you guys getting root 34 for the radius?? I got root 65 by using Pythagoras to find the length of the centre to the point they gave us...

root 34 people, what did you get for the length CT?
That's what i did 🙋
16. (Original post by Dynamic_Vicz)
That's what i did 🙋
People who got √34 likely got √50 for CT.
17. (Original post by yelash)
Yeah I did that as well, seemed too simple at the time after thinking about it for a while. I said straight away the diameter would be 2*radius so using midpoint formula seemed than doing the midpoint thing below. Plus helped on the next question as I had already considered the gradient as -7/4 which made it easier to get the equation of the tangent to the circle. It was something like y-1=4/7(X+2) which simplified to 7x-4y+18=0
Hi guys, so i didnt do any of those things and i got the same answer( i used the x and y values that were being added on from a, i believe that was the point given, to give c and so added those values onto c to give me the new point.
Do you think i would get the full 2 marks for it?

Don't see why not - you used a valid method. I did the same - I thought that as A is across by 7 and up by 4 from C, B must be across by 7 and down by 4.

Area under curve was 81/4
Area under line was 9

81/4 -9
= 81/4 -36/4
= 45/4

In case you guys want it. Technocrat Notes have Finally an apple appstore
app yes!! It has really got me to stop stressing about these hard new spec exams.
