No offense pennybridge but Thank you captain obvious.
To Symphony,
You will be ok as long as you didn't submit it which I'm sure at this point it wouldn't matter if you did submit it because all schools are way past their deadlines.
That said, the only thing that will be saved is the username and password to get into the system. Your Login ID and password can be used for your new stuff. Also, some personal info that you used when you registered for a login and password will be saved into AMCAS. Since this isn't a previous amcas you submitted, you will have to resubmit all the information you put in the 2007 application. Only reapplicants who've submitted an AMCAS in the past will have all of their information saved should they reapply.
