Ditto the Above! Good Luck to Everyone!
To echo what has been said here too many times to count!!!!!!
DO NOT APPLY UNTIL YOU ARE READY AND DON'T APPLY THINKING YOU'LL MAGICALLY BE THE ONE WITH POOR STATS THAT GETS ACCEPTED!!!
Almost everyone has a great hardship story, shadowing experiences, an ah-ha moment, etc. don't rush to apply early just to be early and be one of the 60% who get rejected.
If you are a re-applicant make sure you don't submit the same exact application over again. It didn't work the first time and likely won't the second. Also make sure you point out how you have improved and what you've learned since last year.
All the best!
