Advice on emailing admission? Homeschool and international student

<p>I'm homeschooled and a future international student. I'm going to contact admission because I can't provide some of the requested application materials, and I have questions about applying. Anyway, I was thinking to write a long email with my educational experience, reasons why I chose to homeschool and how am I doing now etc.. But I don't know if it's okay? Or I'll just write a short email with my questions and a sentence "I would like to provide more detailed information about my educational experience if you want to/it is okay"?</p>

<p>Thanks for helping!</p>
