I can’t find answers from the official site, so I’m hoping someone here might know. Should I email it? Mail it?
If you are submitting the CommonApp, your counselor will upload it there. Alternatively, you can mail it to the Office of Admissions. See #4 on this page: http://www.uh.edu/admissions/apply/apply-freshman/
So, I just send the transcript from my address?? How will they verify that it’s from me?
That depends on how you are generating the transcript. Are you using a transcript service or creating one yourself from a template? Ideally, it would be sent by an outside agency, parent, or counselor…not the student. It should also look somewhat official and perhaps contain a signature and statement of authenticity/accuracy. If you have taken classes at external institutions, those transcripts should be sent directly from those schools. I am sure UH is used to seeing a lot of variation in homeschool transcripts. Contact the admissions counselor for your state if you need specific requirements.
