Explanation:

Budgets are estimates individuals make of their expenses based on the income they receive. It allows them to calculate how much money they need to cover basic needs and how much money they must earn so all of them can be covered. Budgets should be reviewed frequently so that individuals can find out if their expenses are being incurred correctly or if there are adjustments to be made.

Thus, reviewing expenses every 3 months is not a good idea if people want to keep track of their expenses correctly.
