What is a Credit Score?
A credit score is a 3-digit number that represents your creditworthiness based on your financial history. It shows how responsibly you manage loans, credit cards, and repayments. Lenders use it to decide whether to approve your loan or credit application.
In simple terms:
Credit Report = Full financial history (detailed record)
Credit Score = Summary (3-digit number based on that report)
