I just started the challenge, but I've already made so much progress!
My score finally reached 670 on the AMEX app, gonna try requesting a CLI again by next month. Waiting to get my $10K Tower Federal Credit Union Mastercard that will lower my aggregate utilization.
It was a busy month. Paid off my Upstart loan (woot!). I will get dinged for credit mix now that I have no open installment loans. Finances over FICO! Also got all the cards (4) I took out balance transfers on to pay off my Upstart loan below 88% utilization. None of this has reported yet but scores should stabalize now that all my moves have been made and will start going up as I cross utilization threshholds in the coming months.
