S1 June 2011 Edexcel - Model answers and common questions in the FIRST POST

you are a Star! tbh am not testing you , coz am doing S1 as a private candidate and life gets tough when i come around such que.

Hey do any of you guys know how to do this?
SURDS
square root of 63 Plus square root 28 minus square root 7

my teachers obssessed with miley cyrus...

Yes, however, think how happy you'll be if you check Arsey's solutions and you've not made a single mistake (that you can remember)?

What a dilemma.

would you have any tips for d1?

use sharp, pointy pencils so you can write fluently (not blunt ones). The pencil is because you can rub mistakes out, fairly obvious. And take a sharpener with you so you can sharpen your pencil at the end of every 4 questions, so you can keep drawing/writing fast with a good feel

that's what I'm gonna do anyway... hopefully I can get a good pass in this module

Which part of the question are you stuck on?

hate drawing activity networks from precedence tables, can never get it right first time round - pencil is invaluable there

3 months ago i used to think im gonna fail D1 , now im pretty much ready for anything in D1 , no matter how hard i try i cant finish a paper in less than an hour which is quite good since it means i dont have to sit around for half an hour + doing nothing like in c2 m1 or s1

I'm guessing he's fairly open about that? if I were him I'd keep that a secret

k u know the equation y=mx + c....well in statistics they kinda just changed it around to y=c + mx....
umm so normally they will say in a qs express the regression line like this p=a + bt.....
so to find 'b' u need to do Spt/Stt cas the normal equation for finding 'b' is Sxy/Sxx...so if u look at the equation of y= c + mx u normally devide Sxy but the 'x' Sxx not Syy.....
so if the equation was written t= a + bp then it would be Spt/Spp....as its the 'p' is the 'x' value...

sorry for waffling but hope it makes sense kinda hard to explain....

Thank you so much !!!!

does anyone know if we can use Casio 991ES PLUS in this exam and also in Core 2? thanks
