eh. method marks hor... if for e.g... that quest on "percentage reduce"....my values are wrong...but my method is correct (value difference/initial value *1...

oc=4op
1/9

then i choose Q10
-2.2 or 23.2
gradient = -9.6

thats about it
very easy, but i know i got some careless here and there

fstein SG

the similiar triangle area ratio is not 1/9

it's 1/3

0.5 x H x 1
-----------------
0.5 x H x 3

cancel out 0.5 and H you will get 1/3

and the relationship of o, c and p is that they are all collinear.

and huai ur tax so much?

question 4 x cannot be -8 (negative so NA). so it's 10 only.

question 3 the t question got +/- sign

AndrewPKYap SG

one O level told me she finished section one in 1/2 hour and decided to do section two slowly... but still finished it in another 1/2 hour...

but on checking, found 4 careless mistakes that she corrected.

the paper really that easy meh?

fstein SG

yeah quite easy.

fstein SG

the star question about the symmetry,

the diagram got a rotational symmetry of 5 and got 5 lines of symmetry.

spadeTwo SG

its VERY easy. Embarassed

one of the easiest O levels paper i ever did when doing my TYS.
from 1999-2006, think this year will be considered easiest liao.
got some ppl in other class still say got confidence get full marks nia.

AndrewPKYap SG

so after moderation, the requirement for A1 is 95 and above? Rolling Eyes

rain-coat SG

wth? where got easy? it was easier than P1 but not that easy ah…

spadeTwo SG

my teacher say those in the good sch sure higher than 95% de
cuz its too easy
so we want get our A1.... is not that easy. Rolling Eyes

abyone SG

ya.. paper 2 was easier than paper 1. Haiz... looks like i can't get A2 anymore... confirm B3 liao Crying or Very sad

I also feel that this year's paper was the easiest... All those tough questions didn't come out..

No questions on Compound interest, Interests, Transformations, Variation... bla bla

spadeTwo SG

transformation and variation got come out in paper 1 Rolling Eyes

AndrewPKYap SG

That's the problem when you take overseas set papers. The people setting the paper set it according to the average standard fort the whole world. This means that Singaporean students have a raw deal because the have to study so much more (study for a much higher standard) than is required.

The students could have used their time studying for this (higher than required standard) for something else. In that way, in this case, I will say the MOE sucks when it comes to e-math.

eagle SG

MOE sucks in everything la

spadeTwo SG

eagle, u in Sgf so long, you should know you cannot type so sensitive comments hor.
^

dahliamorie SG

both paper 1 and 2 tough to me. die lah. Crying or Very sad

abyone SG

ya... i noe.. i meant for more tougher ones in paper 2

spadeTwo SG

this paper too easy
Confused
sure moderate until damn jia lat 1
btw, join in the thread in hwz, its moving much faster.

felirox SG

since most of u said the paper 2 was easy..so after moderation..wad will be the requirement marks to get at least c6?
