Improve your credit score

Improving your credit score takes time and a lot of hard work. There are no quick fixes to improve it immediately. You will need to get a copy of your credit report, and thoroughly look it over. Be sure to dispute any information listed on your report incorrectly.
Your payment history accounts for 35% of your credit score. Make sure you make your payments on time. If you are not current on your payments or have a late payment be sure to get current and stay current.
Amount owed accounts for 30% of your credit score. Keep all your revolving account balances low. Keeping credit cards around 15% or below your credit limit will help significantly. Pay off your debt rather than moving it around. Don’t get more credit cards to raise your credit limit, doing this will most likely backfire.
Re-establish your credit history if you have had problems.
Opening new accounts responsibly and paying them off on time will raise your credit score in the long term. However don’t open too many new accounts in a short period of time, as this will hurt your credit score.
The longer an account is open and paid on time the more it will raise your score.

Good luck, and be patient
