if the grade boundaries are high then the full 100 ums mark would be lower than low grade boundaries years if an A was 59 a 100 ums would be 73-74 but if an A was 64-65 an 100 ums would be 70-71 -
GRADE ME !
Biology Chemistry A , Since The A boundary is from the mid 50's to early 60's Physics depends on the thereshold if it was 50-52 as people suggested u would get an A if it was in the 60's u will get a C if it was in the late 50's u will get a B -

OK Guys when finding Q i made a silly calculation mistake and ended with a wrong X therefore equated in a the equation and got a wrong y so how many marks will i lose assuming i found the Gradient and equated it to the derivative and tryed to solve it ? its out of 5 -

Ya Integeration constant i got 7 or 8 forgot Point Q Was 1-(1/sqrt(x))=2/3 so by solving it u got sqrt of x=3 therefore x=9 and y=-1 u subtisute in the equation the gradient we equate to was 2/3 right ? and the dy/dx was 1-1/sqrt(x)?? Sigma i got 5+9+17+33= (i wrote 59 by mistake its supposed to... -

well do u remember last question what was the derivative ? :S i need to confirm smthn -

Guys Last Question what was the equation we need to deffreiniate ? anyone can remember plzzzz -

guys whats the equation of the derivative used to find point Q ? -

Guys Equation of the derivative to get point Q what was it :S ? -
C1 & C2 discussion - Jan 2013
dude do u remember the derivative used to find the point Q i forgot what it was the one we used to equate to 3/2 -
C1 & C2 discussion - Jan 2013
guys does anyone remember the derivative equation used to find the point Q was it 1-2/sqrt(x)? or smthn can someone post it -
C1 & C2 discussion - Jan 2013
noo its right -2 sry :P im not sure i think 2 or -2 forgot -
C1 & C2 discussion - Jan 2013
yes because its -4x^2 u have to divide by negative one and change the inequality sign and find k's then choose the area inside which is smaller than 6 and bigger than 2 i think -

some people found it hard its gonna have a med grade boundary probably 57-59 out of 75 for an A :P -

mm the 2^y we just multiplied the equation we had above the 8 with 3 so i think 6y+3 or smthn it became the sigma notation i found A1 when i added them up messed up a digit :S although it just a mark the graphs u just shift it down and u draw a line which cuts x axis at -0.5 and y axis at 2 or... -

completting the square was 4(x+1)^2 -1 i think -
C1 & C2 discussion - Jan 2013
i think before the last one it was to integerate and the point which the line passes through was x=1 y=7 i think -
C1 & C2 discussion - Jan 2013
it was eventually -1/4+4/5+something+c=7 i think so 4/4 is equal to 1 maybe u didnt simplify the fraction -
C1 & C2 discussion - Jan 2013
Guys for the integeration questions what did you get for c ? was it -7 or 7 ? forgot which one
