I was homeschooled, never attended high school, and had been taking classes at my local community college for a while - during the ages I would have been in high school if I'd been traditionally schooled - before transferring to my current university. Filling out the "high school" section of the form was a pain! But as far as I can tell, it didn't affect anything- I had my 4.0 GPA from my community college (as you, collegechick_md, will have a college GPA from your freshman year), and any time it came up during recruitment conversations, being able to chat about homeschooling made me stand out from the crowd!
