Every improvement in efficiency is a much need speed boost during any subtest. The two-sided laminated A4 sheet given to you is one such opportunity to improve your speed.
Many will use the laminated sheet carefully to write out the code from English, or literal English translation from code. You will have the time to do this, but after a while rewriting the word ‘opposite’ or ‘negative’ will be tedious and time-consuming.
We advise that you use shortcut symbols to denote operator codes such as ‘opposite’ and ‘negative’. Other notations may be used for ‘female’ and ‘male’. Use these shorthands in your practice sessions. Any time saved in the process can be spent on answering the question.
