A credit score is a number given to you by a consumer reporting agency. Creditors check your score to see how likely you are to pay back your debts. They use it to decide whether to lend you money. Your credit score is based on the information in your credit report.
High credit scores are good, and low credit scores are bad. Usually, the lowest score you can have is around 300, and the highest around 850. Good credit is usually considered 700 or more. Sometimes, credit scores are turned into a letter and number combination. In this system, R9 is the worst credit rating and R1 is the best.
