-level Math Exam Technique

xaminers use certain words in their instructions to let you know what they are expecting in your answer. Make sure that you know what they mean so that you can give the right response.

rite down, state - You can write your answer without having to show how it was obtained. There is nothing to prevent you doing some working if it helps you, but if you are doing a lot then you might have missed the point. Calculate, find, determine, show, solve - Make sure that you show enough working to justify the final answer or conclusion. Marks will be available for showing a correct method. Deduce, hence - This means that you are expected to use the given result to establish something new. You must show all of the steps in your working. Draw - This is used to tell you to plot an accurate graph using graph paper. Take note of any instructions about the scale that must be used. You may need to read values from your graph. Sketch - If the instruction is to sketch a graph then you don''t need to plot the points but you will be expected to show its general shape and its relationship with the axes. Indicate the positions of any turning points and take particular care with any asymptotes. Find the exact value - This instruction is usually given when the final answer involves an irrational value such as a logarithm or a surd. You will need to demonstrate that you can manipulate these quantities so don''t just key everything into your calculator or you will lose marks. If a question requires the final answer to be given to a specific level of accuracy then make sure that you do this or you might needlessly lose marks.
