Aptitude tests are designed to measure job-specific abilities e.g. numerical, verbal, spatial, diagrammatic, abstract reasoning, and data interpretation.

Since practice and familiarity with aptitude tests can significantly improve your performance, the best advice is to start doing sample tests as soon as possible. Many employers provide past papers and there are numerous relevant publications and much helpful information available in bookshops, libraries, and on the Internet.

To prepare for verbal reasoning tests, you should also work on synonyms, antonyms, crossword puzzles, and reading comprehensions.

In numerical tests you will be expected to be familiar with ratios and percentages. Mental arithmetic is important, so you should be able to add, subtract, multiply and divide with speed and precision.

Since there are strict time constraints in aptitude tests, it is important to work quickly and accurately. Always use a watch when practising and during the test itself.
