Tests always begin with instructions and practice items, but if you are unsure of anything ask the person running the session, before the test starts. If you make a mistake on a test item, you will have the chance to work through the question again. If you do not understand the instructions, ask for clarification. Always work as quickly and as accurately as you can, paying careful attention to each question. Concentrate on the task you have been set, remembering the rules you have been given.
Most wrong answers occur because of carelessness.
However, if you are held up by one question, do not spend too long on it, but skip on to the next. Whereas aptitude tests measure your maximum performance capacity, other tests examine typical or preferred behaviour. This second type is strictly speaking not a test because there are no right or wrong answers. When employers assess an individual's preferences for different types of work activity, their opinions and attitudes, or how they tend to react and behave towards others, their interest is in your usual way of approaching situations or people. Interests, values and personality are usually assessed by means of questionnaires without time limits.
