Yep, I got the same.

 

[miss giggles]

Maths was not too hard but not too easy. medium i say.Multiple Choice was really easy, the last questions on the paper were probably the hardest. Anyone get the question about the cube's size differences or something like that? i said something like 38.

i got 36 for that question i did 1^3+2^3+3^3

but what about the question after it the very last question about the equation for number of different size cubes in each cube ,i got n^3 but i think its wrong

 

[sfernando]

IDK but how i got 2000 some where for the cube question!! is simply put 14 cube is 2400 or something ( im worng maybe!!)

 

[silence--]

easy paper. haven't noticed any mistakes yet so let's hope haha

 

[s2 SEductive]

SHIT.

I did not see that extra triangle going through the middle of the diagram. I just assumed the square was added in to make it look complicated BECAUSE IM AN IDIOT. I wrote the answer was 60.

Damn you had time to think off all that
nice
Very smart

what was the answer for the non clac perimeter of the trapezium THE 740CM SQUARED AREA ONE
WAS IT HARD OR IS IT JUST ME AND YEAH I GOT MY ANSWER IN SURDS AGAIN

 

[s2 SEductive]

ughh.. those square and cube questions were horrific
overall i think i did quite well though

what was a reason that the girl was wrong for saying her team had a 1 in 12 chance of winning or whatever?

and can someone please walk me through the last question of that tiles/pavement question?
i got it right to a certain extent... my answer was out by a decimal place and had a 0 missing from what the answer should have been :S

That 10% crap yeah i was lost LOL

i seriously had no idea for the probabilty question too
i just wrote less people on their team
and athletic ability
SOo wrong...

Re: Mathematics - 2009 SC - Opinions and Thoughts

i didnt get the rule for the last question? what was it?

also the 2nd last question in section 1 where it asked for the angle x in that equilateral triangle above the square. what was it?

the rule for the last Q was 1^3 + 2^3...... n^3..

fuck i couldnt believe i put like (1^2 + 2^2 + 3^2)^2 for the 2nd last question >_<

it was 45*.... i actually drew it out and measured the angle coz i forgot how to do it... xD

 

[Nerdygirl]

For the trapezium question the formula sheet was of use, I got a whole number. Though can't remeber all question details so can't say how I worked it out.

 

[Kanane]

I found that test quite hard D:
Everyone from my school came out saying that it was difficult too...But thats because we are lowly ranked I suppose (500's)

I was so stressed during the exam and didn't finish non-calc >__>!

 

[miss giggles]

what did you get for non-calculator question about the ratios 11:12 and age difference 15

 

[MzG1zi]

does any1 know if we'll lose marks for doing the questions in pencil ?
cause our test supervisor only told us today that we were meant to complete all the tests in pen , and i used pencil for the science multiple choice nd some other questions yesterdai....

 

[MzG1zi]

what did you get for non-calculator question about the ratios 11:12 and age difference 15

umm, wasnt that height difference.
i got that the tallest guy was 180cm.
soz, cant remember his name

 

[hul0]

what did you get for non-calculator question about the ratios 11:12 and age difference 15

its 180cm ithink (180 and 165 coz you multiply both ratios by 15)
but yer i just figured it out after the exam...

IT KILLS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[Hayzazz]

Lol you just multiply 15 by 12... that one was obvious o_____O

 

[miss giggles]

but yer i just figured it out after the exam...

IT KILLS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i know its like in exams i go totally blank but then after the exam i'd figure out the questions i didn't know , i get so angry at myself

 

[timme]

non calculator was not easy but the rest was quite ok
the last two questions i got 36 for the number of cubes and for the numerical expression of the formula i said it could be n^3 + n^2
but thats probably wrong idk..

You had to square root 400 (=20) and then minus one (=19)

 

[4025808]

That 10% crap yeah i was lost LOL

i seriously had no idea for the probabilty question too
i just wrote less people on their team
and athletic ability
SOo wrong...

haha i wrote like it wasn't exactly going to be 1/12 chance of winning, and i said it only might be...

but overall, I think i lost at least 5 marks... but it was okay though..

 

[hul0]

ohh DAMN I WROTE 18
BUT IT WAS A GUESS
BUT STILL I WAS ONLY OFF BY 1
IT KILLS AGAIN!!!!!!!!!!!!!!

"this woman is 40 years, in 10 years she'll be younger than this other dude by 20 years. How old is that dude right now?"
epic fail -_-
