as he said, not all schools require 4u students to do 4u, some school do just in case they drop to 3u and yes it doesn't affect the rank of 2u

NEVER go to these coaching centres that asks you to pay for the whole term or even the whole year unless you know it's really good.

the oblique asymptote should be 3x+3 , i think

when you divide 3x^2 by x-1, you get expression=3x+3+3/x-1, therefore, it approaches 3x+3 as x approaches infinity. the answer is 3x , maybe they think 3 is negligilble when it's added to infinity

how do you know they study FOUR hours at the library ? I mean, it's not really practical to do it unless you have last period off or school finishes early. and it' really hard to study consistently for at least four hours a day.

that should be as least a 5u question:hammer:

sorry i didn't make it clear, since the constant term is 4 , which comes from the multiplilcation of the roots. so there must a a factor of 4 that is root. after you find the root using trial and error, which I found was -1, you divide the poly expression by s+1 (factor theorem)

trial and error using factors of 4, and -1 works thus we can divide the whole thing by x+1

how do you type in stuff like that?

PMed you

+1 actually yr11 isn't so stressful

there IS something wrong with going to school and bludge, and study at home!

I don't think there would be enough teachers capable of teaching science extension, based on the fact some teachers can't even teach 2u course properly. It might be just like a course like 4u maths in which a lot of students rely on themselves or tutors

+1 well, how about the contributions made by some random dudes? and chem? effects on society?

it's called science for a reason, instead of social science :spin: +1

was it much better before the syllabus change (initiated by some idiot that doesn't know anything about the subjects) ?

+1 and there shoudn't be these 7 mark questions on some impacts on society which makes it a SOCIAL SCIENCE:chainsaw:
