oh really?! i thught you had to multiply that answer by 1.602 x 10^-19 to get the number of photons.. SIGH!! went a step too far..

yeah.. so anyone remember what/how they got an answer for that question?? it kinda threw me off :D THANKS

yeah definitely! the cut-off for band 6 have been around 70-75, so if you're expecting an 83, you're on a good path nice job brah :D

khorne's answers are 100% correct although i got 11 and 12 wrong :/ CONGRATS KHORNE! WOOOHOOOO

thanks slyhunter! :D +1 rep for you hehe

what would 115/120 scale to?

hi! what would 72/84 become? made silly mistakes here and there :/

as harsh as it may sound, if you leave out the +c they deduct marks :(

question 9bii) was 8litre and 6cv) is -2

for question 4(e) could you also have written abs(x) - 2 <= 0 4 - x^2 >= 0 yes? no?

that's 8c(ii) LOL

me thinks probably 1 for x-intercept 1 for min. turning point and 1 for showing curve approach the x-axis :D

hmm i thought they meant conscutive days, including 2 consecutive days as well so i did 1 minus (probability of wearing the same shirt in 2 or 3 consecutive days) i.e. 1 - [P(RR) + P(BB) + P(RRR)] siiiighh was a bit unclear for me :/

can i ask how you came to that answer in question 5b(iii)

there is no point of inflexion at x = 1 it's just a x-intercept, minimum turning point at x = 3 and approaches x = 0 like the one shown above by the nice fellow :)
