NameSimply requires the technical name for a

process, a chemical etc

State

State means you need to give only brief

answers. This means that, detail explanations

are not required. Only requires a simple

statement, no reasoning is expected.

Calculate

Used when a numerical answer is required. In

general, working should be shown, especially

where two or more steps are involved.

Meant

You need to remember only certain sentences

used which are to conclude all aspects which

are required. Only a formal statement or

equivalent paraphrase is required.

CompareYou need to state the difference or similarity

about two things.

Explain

Explain means that the details explanations are

required to support a statement given.

Important points/information need to be given

specifically. General ideas are insufficient

Complete

Usually used where there are missing items

in a table, diagram or words in a sentence

paragraph.

Determine

Implies that the quantity concerned cannot be

measured directly but is obtained by

calculation, substituting measured or knownvalues or other quantities into a standard

formula.

Suggest

Can be used in two main contexts, i.e. either to

imply that there is no unique answer, or where

this may not be formally ' in the syllabus', but

the examiner thinks the candidate should be

able to apply his knowledge to make a simple

deduction.

Describe

Requires the candidate to state in words (using

diagrams where appropriate) the main points

of the topic. It is often used with reference

either to particular phenomena or to particular

experiments.
