Six mark questions

Six-mark questions are often the questions that people find the most difficult. In all longer answer questions, but especially the six-mark ones, it is important that you plan your answer and not just rush into it. After all, you would plan an essay or short story before starting. Without a plan it is easy to stray away from the key point and lose marks, get steps in a process in the wrong order or forget key bits of information.

Six-mark questions will start with command words such as 鈥楧别蝉肠谤颈产别...鈥 or 鈥楨虫辫濒补颈苍...鈥. The command words 鈥楧别蝉肠谤颈产别...鈥 and 鈥楨虫辫濒补颈苍...鈥 can be confusing. If you are asked to describe a graph, you will be expected to write about its overall shape, whether it is linear or curved, the slope of gradients etc. If you are asked to explain why a pattern or trend is seen in a graph, you will be expected to use your science knowledge not just say what you see (which is a description), eg The graph shows the number of radioactive nuclei decreases as time increases. It does this because...

Explain how and why questions often have the word 鈥榖ecause鈥 in their answer. Describe questions don鈥檛.

The number of marks per question part is given in this form [6 marks]. It is essential that you give as many different points in your answer as possible, linking these together. Often, you will be asked to compare two things: make sure that you include both in your answer otherwise, you are likely to limit your score to two marks out of six.
