No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Usually the only quick fixes are low utilization and removing baddies. Rest comes with planning and more time.
It seems you have 3 credit cards, and you have 2 posting higher than $0. Search the AZEO method (all zero except one) on this forum for more details, but here is the nutshell.
Only one card should post an amount. The rest report as $0. The card that reports is best if it is your card (not AU) and is not a store card. You need to let $5 - 8.9% post. Get it far enough under 8.9% so the interest doesn't make it go over.
No guarantee but this gets most people 5-10 points. I know you said you are practicing AZEO, but it seems you are practicing AZE2 and that is only possible with 7+ cards to get same benefit as AZEO.
