Does anyone know the ACS IP Program cut-off last year? Was it 253?

Yes

Thank You Ms Tay.
My DS got 255 and got MOE SMS for ACS \"Express\" but was wondering whether he will get IP or not.

My DS got three A*, but got only A in MT and ended up with 255.

Looks like most kids have done well in MT this year?

Hi All,


For the following question, I thought the answer should be 1) A only. My DS also think the same way. But the answer key says the right answer is 2) A and D

For setup D, I thought there is not way for the water to evaporate from second tube while some water can be evaporated from the first one. But for setup A, the the amout to water that can be evaporated can be same..

Can some body help me why 2) is correct than 1) ??

I share the same answer as you.

My reasoning is as follows :
For any experiment conducted, we must ensure that it is a fair test (implicitly \"understooded\")
For a fair test, only 1 variable can be changed.
For D, there are 2 variables that have been changed. (therefore not fair test)
(in experiment, we cannot allow any possible source of error and the easiest way is to stick closely to the requirement that only 1 variable is changed)

Thanks atutor2001 and tianzhu for your suggestions..
