Your credit score is a numerical representation of your creditworthiness. It is used by lenders, landlords, and others to evaluate your ability to manage financial responsibilities. A high credit score can make it easier for you to obtain loans, credit cards, and other forms of credit at favorable interest rates. On the other hand, a low credit score can make it more difficult for you to obtain credit, or may result in you being offered credit at less favorable terms. A low credit score can also affect your ability to rent an apartment or even get a job.
