Having a good credit score is important for accessing credit and securing loans with favorable terms. To build a strong credit score, start by paying your bills on time and in full each month. Keep your credit card balances low, as high balances can negatively impact your score. Limit the number of credit applications you make, as multiple inquiries can hurt your score. It's also a good idea to check your credit report regularly for errors and to dispute any inaccuracies.
