Face it, you didn't need any 3 unit knowledge. And actually, I believe that he 2U kids have an advantage in that the only material they must study is 2U.
Most of the questions were easy 2U and a hell of a lot of the paper was year 11 work or even work which you should have done before (ie
ythagoras).
See most of the questions could be solved using very simple 2U methods. All you had to do was see the simplest method
.
For example, have a look at question 8b. I hear lots of people talking about polynomials and all kinds of other things when there is a very simple way of doing that question. They even told you to consider the difference of two areas. All you had to do was find the area of the circle in the 1st quadrant (which is year 7 work at most, A=PI.r
2, then divide that by 4 to get the area in the 1st quadrant), and then you had to substract the area under the curve from 0 to 1.
So SHADED AREA = [(1/4).Area of circle] - [Integration of curve from 0 to 1]
See that is really basic 2 unit stuff.
Question 10 was far from impossible either. There was a very simple YEAR 11 method doing (10.a.i.).
All you had to do was sub the equation of the line with the equation of the curve and then use the year 11 roots of quadrilaterals thing.
ie:
y= x
2
y = mx+b
Solving simultaneously
x
2 = mx+b
x
2-mx-b=0
Finding the roots of the equation,
A+B = -b/a = m
AB = c/a = -b
And that's it! It's purely year 11 stuff. The rest of the question wasn't too hard either.
I'm not trying to brag, I'm just saying that a lot of you complicated questions when there were simple ways of doing things.
I think it all comes down to a lot of 2U students trying to remember all the formulas, without having an understanding of where the formulas come from.
All you need to do is spot the simplest way of answering a question and then use the knowledge you have to solve it.
