Do colleges exist that don’t require any transcripts?
If they do they are likely for profit schools that will take your money and issue you a worthless piece of paper.
Which transcript are you missing? High school? College?
Do you want to work toward a college degree, or do you just want to take some classes that specifically interest you? If you don’t need a degree, ask at your own local community college. Most classes in the Continuing Education division will not have any requirements for admission. It also might be possible for you to enroll as a non-degree student in the credit division.
Don’t fall for scams that promise to enroll you without a transcript.
If you have poor grades, you can still enroll in a public community college set up as a second chance option.
You’ll meet students who are completing their education toward a 4-year college and returning adults who want to change careers.
Community colleges serve their community: if you’re willing to work on your academics, graduated high school (regardless of transcript), and are over the age of 18, you can enroll. They won’t judge you for your transcript but they’ll need it to assess where you might need help to suceed.
