same..cuz if easy test no skills..only test u careless..hard test iq so those not so good one can be filtered out -
today's e math paper two is at 2.30pm right?
-
yeap.Originally posted by jaydunkfull:today's e math paper two is at 2.30pm right? -
gd luck every one!
leaving for sch le.. -
how come the paper so long? during prelims mine was only 2h
-
full mark already! if never get a1, i chop off anything u say.
-
filter out them!!!!Originally posted by Classyfied: same..cuz if easy test no skills..only test u careless..hard test iq so those not so good one can be filtered out 
-
got the similarity and congruency question and teh number pattern question dont know how to do
-
eh orange asterisk, how come you have access to a computer so quickly after the paper? you bring laptop to school or you chiong home after paper?
-
no. pattern: 5+10+15....500Originally posted by jaydunkfull:got the similarity and congruency question and teh number pattern question dont know how to do
simple solution: LET 5 be X
5+10+15...+500=x+2x+3x...+100x
T100=ans for iii x 5

NAME THE QUAD IN QN 4!
ME! TRAPEZIUM!!!!!!!

no. pattern: 5+10+15....500
simple solution: [b]LET 5 be X
5+10+15...+500=x+2x+3x...+100x
T100=ans for iii x 5 [/b]
and i also wrote trapezium for qns 4 -

Non-multiplys of 5: 500-100=400
Sum of non mitiply of 5: subt in 400 as n. -
Can anyone beat me?
They say make use of 5050 right, and i cant see the link between 5050 and 5+10+.... WHATEVER CRAP.
so you know what i did?
Press calculator!!
then (luckily press quickly and accurately) 25250 (or something like that)
then i see how to derive 25250 from 5050
then i see its multiply by 5
So can anyone beat me? -
u can also see it as ( 5 + 10 + 15 + ..... 500 )/5
which means its 5 * ( 1 + 2 + 3 + ..... 100 )
then for the non multiple of 5Originally posted by Darkness_hacker99:I worte, multiplys of 5 : 500/5 = 100
Non-multiplys of 5: 500-100=400
Sum of non mitiply of 5: subt in 400 as n.
just use the ( 1 + 2 + 3 + .... 499 + 500 ) - the mutiples of 5
faster -
Huat ah! A1 already!
-
But this year's paper sooo much easier than the past few year lor. Later moderation till A1 = 85 mark then sian liao.Originally posted by coldzero:Huat ah! A1 already! -
Well, dont even talk abt A1 being 85.Originally posted by Darkness_hacker99:But this year's paper sooo much easier than the past few year lor. Later moderation till A1 = 85 mark then sian liao.
Maybe A1 can be pushed right up to 90.
Heard some ppl say push up to 94, but sounds a bit far-fetched. -
Paper 1 is more difficult as compared to previous years. But I still can do la.. And for Paper 2, 90+/100 is secured for me.
-
on the contrary, paper 1 is like normal o lvl standrd to meOriginally posted by coldzero:Paper 1 is more difficult as compared to previous years. But I still can do la.. And for Paper 2, 90+/100 is secured for me.
paper 2 is more difficult as compared to the previous yuears.
i dun want to discuss any answers abt paper 2 yet, until i get my qn paper tomorrow. -
the paper was manageable lahjust hope they won't shift the bell curve too drastically

lol. u win already lor. slowly press. -_-.Originally posted by gohby:Can anyone beat me?

actually i wanted to do so
-
nono lol. i hvae been trained to press the calculator fast enough. luckily pressed all digits in 3 minutes without any errorOriginally posted by Orange*Asterisk:lol. u win already lor. slowly press. -_-. -
3Min is ALOT of time for 1 sub-part question.Originally posted by gohby:nono lol. i hvae been trained to press the calculator fast enough. luckily pressed all digits in 3 minutes without any error
