Command Words

When reading a question you should 'BURG' it to make sure you understand what it is you need to do in order to gain full credit. This is an extended version of BUG (aka HUG) to deal with calculate questions. It has been designed to be done with just the one pen, so you don't have to keep switching to a highlighter etc.

Box Command Words

These are the words that tell you what to do also known as an imperative.

Underline Keywords

These are any words that key to that question, or instructions

Ring Data

These are any numbers (and their units) in the question or what it wants you to calculate. Draw a largish ring so that you can add the symbol for that quantity.

Go back and check

Check you haven't missed anything and check the number of marks for that question.

The following command words are taken from Ofqual's official list of command words and their meanings that are relevant to science. In addition, where necessary, AQA have included their own command words and their meanings to complement Ofqual's list.

Calculate

Students should use numbers given in the question to work out the answer.

  1. Ring all the data in the question.

  2. Then put your ideas in order using a flow map.

Approximate Mark Scheme:

  • Give some details.
  • Multiple stages.
  • Most of the detail.
  • Correct sequence.
  • Nearly all relevant features.

Choose
