Your credit score is a number based on how well you pay back loans on time, sometimes called a FICO score. The higher the score, the less risky you are. The 3 players are Experian, Equifax and TransUnion. Your goal is to get above 620. That's the line for creditors. If you are below 600, banks won't loan you money. In fact, if your mom knew your credit score was that low, she wouldn't let you borrow any money, either.
