Transcripts and grades

Recently I’ve transferred to a CSU, and forgot to submit my transcripts. I’m currently taking classes at the CSU, but have been received a hold on my account till I submit them; I have a few failing grades on my transcript, will I not be able to attend this school anymore if they see those grades even though I’m taking classes at the CSU already?

Did you report all your grades when you applied which is a requirement? If you reported the F grades and the CSU accepted you, then you should be fine unless there was some conditions on your acceptance by passing these courses in which you failed.
Are these failed courses CSU transferable? Were these courses in your last semester prior to transfer?

Until you submit your transcript, you will not be able to continue taking classes at your CSU.
