Rectangular hyperbolas is year 11 maths.
Basic chemical equations is year 9 chemistry.
On your exam, they’ve dumped stuff you haven’t been taught by a teacher.
So for example in year 8, how would you know what quadratics are?
Basic quadratics as in literally pulsing like terms
Then the basic graph
The discriminat
The discontinuation within the discriminat
Not all parabolas touch the x axis
Not all parabolas are normal form like a=yx2
Especially with maths and science, once you start cheating, your grades become way better
Because you’ve cheated
So for example, in year 7 doing science quest 7 and 8.
In year 8, doing science 8 and science quest 9
In year 9, doing science 9 and science quest 10
Then in year 10, repeating science quest 10
Then in year 11, dropping science completely because you failed 1/2 bio
