If you have applied to a state school and have previously attended another college, the school will likely ask you to provide transcripts from your previous school. This will allow them to see your academic history and make sure that you meet their admissions requirements.
Some state schools may also ask you to provide additional information, such as letters of recommendation or a personal statement. This information can help them to get a better sense of who you are and whether you would be a good fit for their school.
If you are concerned about the privacy of your information, you can contact the admissions office of the state school you are applying to and ask about their data collection policies.
