Double digits? At this rate, by the time my son gets to P6, he'll be :imdrowning:
For my sons, it is a drop between 5 to 10 marks for languages. -
Willow:
sorry! I meant P1s next year.notabox:
err...all P1s knew the class they have been alloted to already, don't they?
Underst that the class will stay the same throughout to P2 (enbloc, no change), i think my ds' form teacher said she will follow him to P2 too...
Yes, current P1s will move up to P2 together with their classmates. Teachers may or may not be the same. My boy had a change of form teacher. -

I googled and found a better answer to this qn: reduce the rate of transpiration (water loss via the leaves) in order to keep the flower from wilting.there is a florist qn:
Florists would remove some leaves from their freshly-cut flowers before putting them in the containers for sale. Based on Alvin's experiment, explain why the florist would do that.
The less leaves the flowers have, the less amount of water it needs. therefore it helps them to save water in helping the flower survive.
The experiment was to see whether the number of leaves affects the amount of water being absorbed by the roots.
PROLONGING THE LIFE OF CUT FLOWERS AND FOLIAGE
Prevent wilting and improve water uptake. Extending from the roots through the stem and out into every part of the leaves and flowers are water-conducting xylem cells through which water moves to keep the whole plant turgid. This lifeline of xylem cells must continue to work to prevent wilting and death. For water to continue to circulate, some must be transpired (given off and lost) by the leaves and flowers. If transpiration is too rapid, the
plant wilts and dies. Thus, to keep the flowers, leaves, and stem from wilting, water must be continuously taken up into all parts of the plant but must not be lost too rapidly.

S6169:
The 2nd part of the Q mentioned that circuit will remain closed for a while? I think the circuit will remain closed untill the battery has run down.
a) The doorbell rang when the switch was closed, the circuit became closed. The iron core became an electromagnet which attracts the armature.Jennifer:
[quote=\"S6169\"]I think 2nd part of this this Q is wrong. when the switch is off, the spring metal (the conductor of electricity) still in contact, so the circuit is still a close circuit and everything is functioning.(electric induced magnetic force is still there).
What is the Model answer for the 1st part of the Q? From my boy, I think the answer also inaccurate.
b) Even though the switch was turned off, the iron core remains a temporary magnet for a while, attracting the metal armature and closed the contact, thus making the circuit closed.
For the 1st part of the Q, my son said the teacher mentioned about the resistance when she try to explain the answer.
Indeed, It is too complicated for a P5 student.[/quote]Check out this link, very interesting http://home.howstuffworks.com/home-improvement/repair/doorbell3.htm -

If the kid failed the HCL in P5, will he be able to choose HCL in P6?

I posted the same question to the CL teacher.
Her answer : the decision is not cast in stone yet for those pupils who did not fail too badly. There will be a meeting to discuss, taking into consideration the performance of other subjects and the child's attitude during lessons. -

don't worry. it is more like a roller coaster ride. :evil:

Roller coasters are unhealthy for my aging heart. Carousel rides are more my cup of tea now. Mabbe next yr I go email all the HODs to remind them not to set P5 std for P3 level - it's bad for parents' health, hehe.

Btw even at P2 level, the marking for OE Compre is already set at PSLE std - a minor error will get you zero for the whole qn, no sympathy marks for half-right ans whatsoever. I think a couple yrs back, a parent wrote to ST to give \"feedback\" on this issue too.
Personally I think setting a high benchmark early is good in the long run. Our kids will be trained to write concisely and accurately from lower pri onwards - especially useful for my careless gnome of a son.

FQW:
perhaps you would like to train your heart to be resilient by going for more rides at universal studios :evil: when my son was in p3, the marking for science was already geared towards psle...when hubby asked teacher why answer wasn't acceptable, she just replied, 'not in line with psle standard'.
