Carrying out long calculations can take a significant amount of time, especially in the Quantitative Reasoning as often figures or values given are long and complex, to test your mathematical ability. A useful tip is to round these numbers to the best of your ability, as this will save time and make the calculations easier. For example, if the question asks you to calculate an answer using the number 6893, it may be effective to round it up to 7000. However, this must be used with caution, as sometimes the answer options may be similar numbers – such as 12,125 and 12,500 – therefore you would need to be more specific and consider rounding to a lesser degree in this situation.
