I guess for maths, practice is important so those who practice a lot would find it easier...
Verysuperkiasu:
[quote=\"spunky\"]A* now not 91-100. Now paper so easy maybe 96-100 to get A*
But there is another group who finds it relatively more difficult so maybe T score remains for A* at 91? :xedfingers:

Yeah, just worked out the answer myself. Paper 1 #15 is 24 days. Sigh! My DD got it wrong.
Listing, although it will take longer, is a fool-proof method!
No, the ans is 26 days. this is a trick question. -

DS say the same. 3 more to go, and :xedfingers: :xedfingers:ngbrdad:
Phew DS says he and his classmates found the paper easy.
2 down 2 more to go. -
SAplayer:
Basically the paper had easy questions...only reason why it should have been difficult for some is because of time constraints!
My Gal Says the Earlier Part Q are Harder ....
A Lot of students may spent too Long Looking at these earlier Q, so Not Much Time left to do the Later Q, Which She Says is Very Easy. -

432/8 = 54 remainder 0. So 432 is the last number in a group of 8 i.e. D (oops! sorry last number is A. Thank you Pen88n for the correction.)
