While some colleges might accept unofficial transcripts for initial review or to get a sense of a student's academic record, they will *always* require official transcripts, sent directly from the issuing institution, before making a final admission decision. This is crucial for verifying the information provided on the application.
So, instead of looking for colleges that *don't* require official transcripts (which are exceptionally rare), you should focus on understanding how to request and send official transcripts from your high school(s) and any other institutions you've attended. Each institution has its own process for this, often involving online portals or mail requests.
