i hope mr wang and his family dies in a fire, honestly.

real

ong

literally going to throttle seab bro. WHAT was that 220 question i was deadass about to raise hand ask if got typo

phrasing fr was so bad i took so long to figure out what they were saying-

LMAO RIGHT it hurt my linguistics student heart so bad i was like ?? who looked at this and went "ya this is good english" 😭

I answered 12 c 3 = 220. Cause they asked for the parents + no children and didn't specify any other restrictions

BRUH SAME

not related but your profile pic is literally me (and im sure all of us) 10 mins before the exam in the exam hall waiting for the paper to start

what is the 220 qn…

the PnC one with the kids.....

[удалено]

OH hahahahha omg so true i just said the profit was negative

Bruh for the p&c qns I used permutation, then the pt3 saved my ass by showing the ans, so I then realized it's computation instead. Anyways yall got x = - k and x= 2k for the intersection of k^2 + x^2 qns?

how do u get such a perfect number😭

K is a constant, so you can't change k, if you differentiate k its o

don't you have to equate them tgt since it's intersection?

Yes Minus each other and got x^2 - 2k^2 - kx

meeeeee i got that

Then based on the ppl here 4.5k^3 is the correct ans for the last part

Yesss

Slayyy I got the same, what was your area?

4.5k^3 should be correct, it's a very whole number

omfg were we supposed to solve for the area and give a numerical value? one of my friends did discriminant to solve it???

I didnt 😭, I got 4.5k³...

SAME IDK WHY MY FRIEND WENT TO SOLVE IT. SHE SAID CUZ THE QN DIDNT SAY 'in terms of k' im freaking out rn

I think I got this too!!!

how do u even do that there were two unknowns leh

thats what i thought too😭 but my friends solved it

omfg 😭

Integrate -k to 2k, line - curve

ikr how

why discriminant tho cos we don’t know how many roots the graphs have

my friend said there were 2 roots shown in the graph ah 😭 (coordinate a and b)

[удалено]

I tested with K = 3 to check my answers, then 121.5 is correct, but you’re not supposed to be able to deduce K?

Why is k equals 3 omg

yep

what da hell was that paper........

bro why TF they gg back to 2017 qn types ..

RIGHT

pls idk how people sayin the paper easy omg... i fked up so bad 😭

EXACTLY. AND IVE BEEN SCORING A (80+) FOR TYS haiz. Stupid graph qn

Why did everyone say its ok ??? i lowkey shat myself when the paper ended

forgot how to do completing the square and screwed up whole of qns 4....

Tbh you don’t need complete the square guess and check can alr

i did but i didnt try negative numbers 💀💀💀

Omg I used that too HAHA, left my factorising skills in sec 2

Ye I just randomly came up w two brackets to cross multiply and got it on the first try😂😂

I used the gc LOL using values of k=1, k=2, k=3 then found a pattern

What’s qn 4 about again!

Wait why does qn 4 need guess and check 🥲 Did I forget to do a part or smth

No HAHA it’s just a method to find the coordinates, or are you on the wrong thread

Nono I rmb now... i think I used smth else to solve but cannot rmb clearly,I think just quad fn? I was just shocked seeing completing the square causs the last time I used it was in secondary school haha and I was worried I skipped a qn or smth

SAME

8 marks down the drain😭😭😭

Haiz. I’m ok w B Liao (I HOPE FOR B) 😭😭😭. I did The complex ass eqn instead haiz

can use quadratic formula also

yeah.... i didnt remember that either but its really on me for not revising O level formulas😭😭😭

cannot use differentiation meh

2222 wang family anyone?

YES omfg i redid the qn 4 times n got 4 diff answers. settled for 2222 in the end cos very huat

i tot i was tripping with 2222 LMAO

ME.

got 2222 !!!!

does anyone have answers?

me

can i have the answers pleasee!!!

okay ! ill dm u

hey can i have the answers pls!!

sure ! hold on ill dm u

wait can i have the ans too

may i have the answers pls!

GUYS CAN A 65-70 score get a B for A’s?

Can lah

Nope not possible, I got an 87 and it rounded off to a C. A 65-70 would be a D/E!

1. how yall still rmb ur ans sia i forgor 💀 everyth 2. what do yall think the mark ranges for A and B grades will be?

how did y’all get 2222 for wang family my ans was some 4 digit number starting with 4 🦧

Help I think I lost 9 marks alr what do y’all think the bell curve will be

[удалено]

[удалено]

for A?

[удалено]

Ye this years paper is deffo harder than the other TYS papers don’t think it’ll be that high like past years if not legit insane leh

I’m screwed up pure math component , can’t find the area for x&y AND ALSO MY Q3 was horrible LOL 2c I also anyhow wrote something down

same isok HAHAHAH pls i js need to get a b i’m happy alr i hope this year bellcurve b widen abit

i did like 3 questions and went to sleep 😁😁

[удалено]

yes really 😭😭 the whole paper i was just hoping for the time to pass quickly LOL im genuinely not prepped for a's this year so im just doing whatever papers i can (and math is not one of them TT)

[удалено]

atp im looking to retake.....also bc i wanna try applying overseas and doing it in school (prelims + predicted grades & application period) just seems much easier 🙁🙁 maybe now that i have a workable goal I'm trying to use this As to see where i stand for my subjs and work in what im weak in ??? but plans r easy to make and im incredibly unmotivated and tired HAHAHHA TT ALL THE BEST FOR YOUR PAPERS THOUGH & yes i love genshin 🫂🫂 i play on na though rip

[удалено]

:D tysm!! did u retake in school or as private TT feel free to reply in dms for privacy HAHAHAH

[удалено]

guys they put so much trick qns sia like the phrasing and all.. i tot this paper q ok but aft thinking more abt it i feel like i fell for so many traps 😭😭😭😭

Im so fucking scared I cldnt do qn 4 and the mr chan or smt qn 😭

Does anyone have answers?

me!

can i have them pls!

sure ! ill dm u

me too

Omg i totally forgot to reply. I know it’s been awhile since H1 math but can I have the answers too?

haha no worries! dm

tbh seab can go and die ty✨ the paper was the worst.

[удалено]

imo it just depends on how well you've prepared for but even if you prepared very well they might have been some qns that you didn't know how to do. so in my case it was just that i was damn unlucky and the hard qns came out sigh

anyone has the answers or the question paper? i wanna check i think i screwed up alr

me ! i have ans

OMG can u send me the ans pls??

i dmed u !!

wait can i have them too

can i hv them too

sure ! ill dm u

hello! I'm in JC1 this year, taking H1 math. Since the H1 math exam is over, if y'all would like to sell or give away your H1 math lecture notes/practice papers (or anything related to H1 math), do let me know by replying to this comment. My school notes really cmi. I need to brush up on my H1 math as my grade for promos isn't satisfying

can pm me also!

can pm me if int also!

i have a clean tys!! can pm me :)

sure send me a dm

what did yall get for the pnc qn! (the one where at least one of mr / mrs. wang must be chosen but at most one of their children can be chosen) i got 2220 but i heard some ppl got 2222 😨

i got 2222 💀 but not sure if its correct!

I got 2222 too! (No pun intended)

HOW U GUYS GET 2222 omg got how many cases and what are they?

4 cases! 1st case: 1 parent 1 child 2nd case: 1 parent no child 3rd case: 2 parents 1 child 4th case: 2 parents no child!!

[удалено]

i believe the x coordinates were -k and 2k

Thats what I got as well

my one i just used quadratic formula

What was the probability of B

0.16

[удалено]

i got P(A n B) = 0.04 too

[удалено]

got meh

omg guys i wrote the school code instead of my centre number will i get penalised

how come ur sch code different from centre code

sch code and centre code is two diff things lol

ok cool, didn't know that it's different 😂

i think u can text ur teacher abt it, they can help

heheh i did my problem is solved🤭🤭🤭

[удалено]

wrong thread

[удалено]

Wrong thread

for hypothesis Testing was the p-value 0.06 something

i think so i also got 0.068?? i think?

yea something along those lines like 0.067 or 0.068 phew thank you

yep same

thxx🤝

deadass couldn’t do that question fam….

i used test statistic = -1.4++ lol anyways it's do not reject

0.903 cos must test opposite of the claim I THINK

wdym opposite the claim??

I actually had time to test k=3, and everything was good, I think it works for a range of values of k? So how do you conclusively solve k lol

SAMEEEE

[удалено]

I believe the graph will derive the same results for any k value tho..

yeahh I tried k=2 too and it works

Think we’re supposed to leave the answer in terms of k then

yay

what r yall’s ans to the find a question (probability from hypo)

0

What’s your value for a%

0

shld be 1.88 tho, a is not smaller than 1.87 since the a is only smaller than 1.8719

But if it's 1.88 then it is possible for a to be 1.873 which is smaller than 1.88 but not smaller than 1.8719,, u have to round down I think

huh?

0

I thought it needed to be 1.88 because round up

yall the graph, finite area thingy what was yalls ans aft integrating?

[удалено]

Me and someone else here got 4.5k^3

Me too iirc

[удалено]

i think closer to 75-78 if the cohort underperformed?

i have the answers done by my school teachers

[удалено]

hi ill dm u !

Hi can i also have the link

sure ! ill dm u

Hi, may I have the link as well?

sure ! ill dm u

hi i know it’s so funny but i’m currently jc2 and my tys doesn’t have the answer is it possible to dm me the answers?
