CSU mistake

5 weeks ago I submitted my college applications and seem good when I was finished. On the next following week, my counselor called me during school and gave me a transcript of classes I need to put in my college applications and unfortunately I couldn’t able change it.

You mean you submitted the application with incorrect courses and/or grades based on the new transcript? If you have any mistakes, you need to contact each CSU that you applied and email the correction information. Make sure you get an acknowledgement from each CSU that have received your update and keep all documentation.
