i lost 4 marks because of this!!

inshallah there will be curve and it will be very low and we will get A*........we will surely get the fruit of our hard work INSHALLAH

The percentile will be very high, LOL, what luck! Let's hope we get a difficult paper for math paper4

How many marks can I lose and still get A* do you guys think? (Math paper 2 varient 22)

 

[mutilated_grass]

The 2011 papers was pretty easy but you could get an A* if you lost 20-30 marks IN TOTAL, combining the marks for paper 2 and 4. I think for Paper 2 of this year, losing 15 marks or less would get you an A? You need an A for Paper 4 too to get an A*. My guess is based from my observations at the centre I was in and it differs from centre to centre.

:O... Ok, now a got a new question: If get an A in Paper 2, and an A in Paper 4, does that mean I get an A*? or does it depend on how many grades I lost?

 

[mutilated_grass]

By grades you mean marks right?
Well..logically, the less marks you lose, the more chance you have of getting an A*
But right now, you don't know whether you are gonna get an A in both papers or not.
So getting an A* means you gotta get an A in both papers, means getting really good marks in both papers
This is also where luck comes in
Damn it, why are math papers getting easier every year?

So getting an A* depends on my MARKS, not my GRADES IN BOTH PAPERS, right or did I misunderstand?

 

[mutilated_grass]

For the 2011 winter session, the A* was at 188/200...losing 12 marks in total...well...the CIE people are real smart people..

WHY US? why cant they give hard exams...like in 1990s?

 

[mutilated_grass]

Don't your grades depend on your marks? But yes, your right. Now I gotta stop obsessing over Math and go revise Islamiat.

 

[mutilated_grass]

Ahhh you see, the oldy examiners want less people to get A*'s so they increased the percentile. WHY US? Cuz we get smarter and we have more resources to study from as time passes. To make it challenging and exam-worthy, they made their exams harder too...

 

[Amir Tosson]

Let's just pray that Paper 4 gives us a challenge! I lost 3 marks in Paper 2 today so far :'(

ONLY 3 wow...i lost more... such careless mistakes too

That's why I hate easy exams! You get the hard ones right and the easy ones wrong :s

i g
i got x axis invariant b/c the image was parallel to x axis and in shear parallel to x axis means x axis invariant

It is parallel to x axis and y axis is invariant b/c y axis doesnt change ( its coordinates stay the same )

 

[Ahmedboombox]

Well For the Question concerning the Transformation , I got a shear with y axis invarient and scale factor of 2
(1 0)
(2 1) , I multiplied all the points by this matrice and i got the same exact points for the Image(shear) so i dont know why some people are saying X-axis is invarient.

 

[Ahmedboombox]

For paper 4 , All you have to concentrate in is numbers which is always the first page (A lot of people make mistakes without knowing) , Area just simply practice it , The chapter concerning frequency density and cumulative frequency and we can not forget the probability (also alot of people make mistakes in it ) ,Finally Sequence (It's not very difficult but it requires a relaxed brain because after many tries you seem to give up when the answer is just laying in your mind). Good luck everyone and there is no need to make a fuss about this paper 2 it's already over what's done is done .
P.S tomorrow i have my islamiyat and i just opened the book today (i really had no time for it anyway's wish me luck am going to kill this )

what abt the first matrix????
i got 3.5....

YUP then, +3 -3 then iguess 5
