<p>I’m not sure whether there’s an easier way to do this, but my advice would just be to call collegeboard for help. I was having trouble about a year ago because I had an account from 7th grade for gifted testing and it wouldn’t let me register from another account. Anyway, collegeboard cleared it up pretty quickly and easily, so that should probably work in your situation too.</p>
<p>Here’s the number: (866) 756-7346 </p>
