How do i pay down credit cards to raise my score fast

If I need to payoff my credit card balances to raisemy credit scores, what is the best way? Do I attackone card or put any extra money towards all cards? DoI focus on a higher interest rate card or concentrateon paying off a particular card one by one? If I havea high debt to credit ratio how willing are thecreditor to lower an interest rate. I have never hada late payment, but I do owe too much money.

to rasie you score
pay each card down to less than 80% against your credit limit
if you have a limit of 10,000 pay it down to 7,999
do this for each card.

this raises scores.
