i personally find it Quite easy except for a few part questions which i didnt know how to do.
I think paper 2 will be hell
Ya quite easy. But the question when d=12 what is t is get wrong! I write 4 zzz...
But overall still ok ba. I scared e maths leh. My friend say last year A1 for emaths is 87 marks...
I couldn't figure out the sequence question, and I fell for the trick in question 2. Question said that he sold the watch at 135% profit from cost, I didn't think and put the selling price as 135% of the cost.
There have been disputes for that question. How did all of you guys answer it?
An inverted triangle shaped prism takes 8 seconds to fill completely, and is 24 cm in height. How long does it take to fill 12 cm? Also, draw a graph.

I find it okay...Didn't manage to do like 4 questions which is like 4 marks fly away...but not sure the rest all correct anot =x hope do well for paper 2~~~
For me, t=2. I was rather taken aback by the absence of typical P1 questions like graphs of functions and construction. P2 will probably be as unconventional as P1. =/
wa sian dun like u la
i wanted to post =<
paper was easy as hell .
z.z
knn prepare to die for Paper 2 already. This paper i finish in 1 hr..
the only more challenging question is the one on vectors, the last question.
personally i feel this year PSLE paper harder than this sia
wa 87 marks for A1. if this year also something liddat this, after a few careless mistakes, the A1 will say goodbye liaoz.
Qn2: I also think it's 235/100 x 48
The water triangle-prism qn, a lot of ppl say 2 and other people say 1. and i anyhow do and manage to get 2. i guess depth = k(sqrt t) lol
I get t= 4....then the graph is straight line... towards the end..
the watch i use 235/100 x cost price.
Hope correct =x
anyway these are my spots for tomoro question
graph most probably kind of with 2 turning point (x^3 curve)
circle properties (more of them)
area of a lot of things
polygon
sets notation
trigo
matrices
bearing
probability
and probably another vector question
share your spots here :D

wont be a straight line, it will be a curve, answer is 2
and the watch yupp, is 235/100 x cost price, answer 100+ de, not 64.blah blah that one
Heh, quite a number of my classmates gave a straight line. Btw, how many managed to find that the sequence was 45 - 7n?
nah. i left it blank .
vector was easy.
got the N thingy wrong. they say is - i go put + .

heh i think almost everyone can get 45 - 7n
lol..I use 12/24 = x/8 den cross it to get t=4...den straight line...plus they say is constant rate..Can tell how u get t=2? That question i leave blank LOL
yupp i got that sequence
the constant rate refered to the rate of flow of water.

use similar triangle, let length be x
time taken = 1/2 x 12 x (x/2) x8
1/2 x 12 x (x)
nvm luh
governement say ite got future one
Another thing, for the Population question, second part asked for the africa population over square kilometres. You guys put 31.0 or 31.3?

i rounded off to 31. >.<
I did last year official O lv e math paper as well...This paper 1 is more tricky...
Originally posted by qdtimes2:i rounded off to 31. >.<
same hahas
erm, by difficulty, last year was more challenging. but this year more tricky but hell more easier
I bet alot people think they correct then in the end die -_- this kind of paper is mislead people thinking they score A1 in the end b3 -_- cuz its tricky but not hard..

thats why we are able to finish the paper more quickly, and thereby spot the trick within the paper. so overall its still balance
