First of all, don't panic! You may think that you didn't understand the whole piece, but are there any parts you did understand? Look at the possible answers if it's multiple choice and apply the process of ...

In response to high blood glucose concentrations, insulin is released from the pancreas into the blood. Insulin acts on cells (especially liver cells) and causes glucose to move from the blood into these cel...

First, show how to multiply out two brackets, and the structure of such a question.When given a quadratic, such as x^2 + 4x - 32 (x+8)(x-4)to solve this, first making a list of factors of 32 is important. So...

Know your structure well. -Write a short, concise and definition-orientated introduction-Plan 2 or 3 points you want to discuss and briefly jot down chains of reasoning, alongside potential counterpoints -Us...

i) dy/dx=12x^3-24x^2ii) the stationary points occur when dy/dx = 0 so we must find the solutions to 12x^3-24x^2=0.12x^3-24x^2= 12x^2(x-2)=0Therefore our stationary points are when 12x^2=0 ie x=0 and x-2=0 ie...
