Tks

I suspect Qn printed wrongly. RHS should be (1- tan x) /(1 + tanx).

Can anyone please help me with these questions,

1. 9^y+5(3^y-10)=0
2. 3^2x=16-2(3^x+1)
3. 2^2x=2^x+1+15
Thank you

A rough guide... Use suitable substitution for all the Qn.
1. Let u = 3^y
2. Let u = 3^x
3. Let u = 2^x
Then you can carry on solving using quadratic equation.
Try

HI,

Firstly you have to read carefully. Qn is not asking for stationary point of CURVE !
It is asking for the stationary value for the GRADIENT FUNCTION. :scared:

Solution :
So you need to differentiate the GRADIENT, then equate it to zero for stationary value
Try it, should be ok now

Give you a guide to start.

Move one item to the right.
Take lg both side.
Use power law to bring the power down.
Expand and you will be able to group the lg x together and solve.
Try it

No one in here is using window unit aircon ?

Like to ask if any of you have window unit air con at home ? If so, does it really cool the room ? Is the electricity consumption higher than the compresser type ? Where is the recommended place to buy such unit ?


Thanks in advance.

Though this school is supposed to be SAP, i keep feeling the Chinese teachers are very unwilling to teach properly.

DD is in Sec 3 doing Higher Chinese. Every year without fail, the Chinese teacher will tell me DD should do express Chinese and not higher chinese. I agree DD is not strong in the subject, but don't the teachers have a job to do, to teach the students properly? Aren't they supposed to encourage the students to love the subject and not complain to us that our kids are hard to teach? If DD is already outstanding, then what do we need the teachers for?

Really disappointing. I actually sent DD to this school because all students can do higher chinese. But it is a disguise.
Worse thing is, the teachers have the support of HOD to call us year after year to drop Higher Chinese. They have two HOD in case you don't know.

DD will be sec 4 next year. I insist she keeps higher chinese because it is more useful for JC. Doing express chinese is not useful.

Hi, my DS is also in Sec 3, same as your DD. I have the same experience as you. During the PTM, the chinese teacher would explain why she want my DS to drop HMT but we say try for O lvl and see how. So if Jan, the results is B3 and below, most probably have to drop HMT, then retake Chinese O lvl in June. Keep fingers cross :xedfingers: that he at least can get an A2, then no need to drop HMT

Hi all,


My son's PSLE result is 237, & AHS cut off point based on last year's intake is 239.

Is it worth trying to put AHS as his first choice? Is it risky, & how would appeal procedure be like?

For those who appealed n was accepted, what was the point difference with the cut off point?

Any input, thoughts or advice is much appreciated ^^

Thanks,

Yes, if you really like AHS, appeal in, even if you are allocated your 2nd choice school. You don't try, you won't know
Then only thing is appeal case result usually out quite late, like 27th /28th Dec.

We are considering AHS and would really appreciate if any parents can share your opinion on AHS culture. Since it's a SAP school, I am a little concerned whether my DS who comes from an English speaking home would fit. He got A for CL but did not do HMTL. His other consideration is TKSS which is a big step down versus AHS from COP stand point. Thanks!

My DS also did not take HMT in Pri sch. He has an A for PSLE Chinese. He was offered HMT in AHS, so we give it a try. Till now, he finished his Sec3, he is still taking HMT. For AHS, if student cannot handle HMT, the Chinese teacher will advise the child to drop the subject. So there is no harm to try in Sec1
