A huge bunch of stuff on credit cards
Pay your bills on time. Most credit card companies will take a close look at your history of payment in order to determine your eligibility for a credit card with better terms. Even if you have only missed one credit card payment in the past, your credit rating may be affected adversely. If you want to improve your credit rating, paying your bills promptly is a great way to do that. Pay off any remaining balance on your credit card.
