If you got your scores here. What does it say that is hurting your score. I know TU hates a lot of CCs reporting a balance and it also may be picky on credit mix. EX also looks a total util but I dont think it is as picky on total # cards reporting. Also make sure that all your CC accounts are reported in the same was in terms of type of account, balance and age.
