The creative writing section is some people's favourite part of the exam, and some people's most detested. The key thing to remember is that, above all, the examiners are looking for descriptive language-...

For x!=0, multiply the equation by x to get x^4+5x^2+1=0. Then substitute t=x^2 where t>=0. So the equation has a form t^2+5t+1. Then find the discriminant and two roots. One of the roots t2<0 doesn...

Get a line a form y=-ax/b-c/b, then substitute into a cirle equation (x-p)^2 +(y-s)^2=r^2. Get a quadratic and find whether a discriminant is equal to zero. If it is then the line is tangent to a circle. ...

When talking about a state employing "monetary policy" to achieve macroeconomic objectives (low and steady rate of inflation and growth; low unemployment; stability in the balance of payments), ...

The important part to any History A-Level is the structure, as it not only shows the examiner your understanding of the question but also your level of knowledge. As an effectively structured argument can...
